Thomas Matthew DeLonge (; born December 13, 1975) is an American musician and songwriter best known as the co-founder, co-lead vocalist, and guitarist of the rock band Blink-182 across three stints (1992–2005, 2009–2015, and since 2022). He is also the lead vocalist and guitarist of the rock band Angels & Airwaves, which he formed in 2005 after his first departure from Blink-182. DeLonge is noted for his distinctive nasal singing voice.

DeLonge received his first guitar as a child and later began writing punk rock songs. While in high school, he formed Blink-182 with bassist Mark Hoppus and drummer Scott Raynor. They signed with Cargo Music and released their debut album, Cheshire Cat (1995), which made them popular in the local scene. Their second album, Dude Ranch (1997), was released by MCA Records and featured the hit single "Dammit". Travis Barker replaced Raynor in 1998 and the group achieved widespread success with their third album, Enema of the State (1999), which featured three hit singles; it sold more than 15 million copies worldwide and went quadruple-platinum in the U.S. The band's fourth release, Take Off Your Pants and Jacket (2001), gave them their first No. 1 album.

DeLonge and Barker experimented with post-hardcore music on the album Box Car Racer (2002), which they released under the name Box Car Racer, but the side project was dissolved the next year. Blink-182's untitled fifth album, also known eponymously as Blink-182 (2003), reflected a change in tone. Following internal tension spearheaded by DeLonge, the band broke up in 2005 before reuniting in 2009. During their initial breakup, DeLonge formed Angels & Airwaves, which has released five albums and evolved into what he calls an "art project" encompassing various forms of media. In 2015, DeLonge once again departed from Blink-182 before returning a second time in 2022.

Outside of music, DeLonge has founded companies such as Macbeth Footwear, which sells vegan and organic clothing; Modlife, which sells technology designed to help artists monetize their creations; and To The Stars, which is dedicated to the exploration of fringe science. He scored and produced the sci-fi film Love (2011), has multiple film projects in development, and wrote the children's book The Lonely Astronaut on Christmas Eve (2013).

Early life

Thomas Matthew DeLonge was born in Poway, California, on December 13, 1975, the son of mortgage broker, Constance (née Lovell), and oil company executive Thomas Lyon DeLonge. He has a brother, Shon, and a sister, Kari. He is of German and Mexican descent. His first musical instrument was a trumpet, which he received as a Christmas gift at age 11. He originally planned to become a firefighter, and participated in the San Diego Cadet Program. He first picked up the guitar from a friend at church camp, and became preoccupied by the instrument. He attempted to form a band named Big Oily Men, which was essentially a one-man band because its lineup consisted of whomever he could persuade to join him for short periods. He first began skateboarding in the third grade, After high school, he worked on construction sites, driving a diesel truck and handling concrete and piping: "I hated, hated, hated my job. You know those people who hate their job? That was me." He quit when Blink-182 signed with MCA Records in 1996. The following summer, his desire to be in a legitimate band increased significantly – Anne Hoppus characterized Delonge's passion as "incessant whining and complaining". Her brother, bassist, Mark Hoppus, was new to San Diego and she introduced the two one night that August. The two would jam for hours in DeLonge's garage, exchanging lyrics and writing new songs.

The trio began to practice together in Raynor's bedroom, spending hours together writing music, attending punk shows and movies and playing practical jokes. Hoppus and DeLonge would alternate singing vocal parts. The trio first operated under a variety of names, including Duck Tape and Figure 8, until DeLonge rechristened the band "Blink". Their first demo, Flyswatter—a combination of original songs and punk covers—was recorded in Raynor's bedroom in May 1993. DeLonge called clubs constantly in San Diego asking for a spot to play, as well as calling up local high schools convincing them that Blink was a "motivational band with a strong anti-drug message" in hopes to play at an assembly or lunch. With help from local record store manager Pat Secor, the group recorded Buddha (1994), a demo cassette that increased the band's stature within San Diego. Cargo Records signed the band on a "trial basis"; Hoppus was the only member to sign the contract, as DeLonge was at work at the time and Raynor was still a minor. The band recorded their debut album in three days at Westbeach Recorders in Los Angeles, fueled by both new songs and re-recordings of songs from previous demos.

Although Cheshire Cat, released in February 1995, made very little impact commercially, it is cited by musicians as an iconic release.

The band toured constantly between 1995 and 1996, performing nationwide, as well as in Canada and in Australia. By March 1996, the trio began to accumulate a genuine buzz among major labels, resulting in a bidding war between Interscope, MCA and Epitaph. MCA promised the group complete artistic freedom and eventually signed the band, but Raynor held a great affinity for Epitaph and began to feel half-invested in the band when they passed over the label. Their second effort, Dude Ranch, hit stores the following summer and the band headed out on their first Warped Tour. When lead single "Dammit" began rotation at Los Angeles-based KROQ-FM, other stations took notice and the single was added to rock radio playlists across the country. Dude Ranch shipped gold by 1998, but the exhaustive touring schedule brought tensions among the trio. Raynor had been drinking heavily to offset personal issues, and he was fired by DeLonge and Hoppus in mid-1998 despite agreeing to attend rehab and quit drinking.

Travis Barker, drummer for tourmate the Aquabats, filled in for Raynor, learning the 20-song setlist in 45 minutes before the first show. Barker joined the band full-time in summer 1998 and the band entered the studio with producer Jerry Finn later that year to begin work on their third album. "All the Small Things" became a number-one hit on the Modern Rock Tracks chart, but also became a crossover hit and peaked at number 6 on the Billboard Hot 100 chart. Although the band were criticized as synthesized, manufactured pop only remotely resembling punk and pigeonholed as a joke act due to the puerile slant of its singles and associating music videos, Enema of the State was an enormous commercial success. The album has sold over 15 million copies worldwide and had a considerable effect on pop punk music, inspiring a "second wave" of the genre and numerous acolytes.

After multi-platinum success, arena tours and cameo appearances (American Pie), the band recorded Take Off Your Pants and Jacket (2001), which debuted at number 1 in the United States, Canada, and Germany. Hit singles "The Rock Show", "Stay Together for the Kids" and "First Date" continued the band's mainstream success worldwide, with MTV cementing their image as video stars.

2002: Box Car Racer

During time off from touring from Blink-182 in 2002, DeLonge felt an "itch to do something where he didn't feel locked in to what Blink was", and channeled his chronic back pain (a herniated disc) and resulting frustration into Box Car Racer (2002), a post-hardcore album that further explores his Fugazi and Refused inspiration. Refraining from paying for a studio drummer, he invited Barker to record drums on the project and Hoppus felt betrayed. The event caused great division within the trio for some time and an unresolved tension at the forefront of the band's later hiatus.

Blink-182 regrouped in 2003 to record their fifth studio album, infusing experimentalist elements into their usual pop punk sound, inspired by lifestyle changes (the band members all became fathers before the album was released) and side projects. Blink's eponymous fifth studio album was released in the fall of 2003 through Geffen Records, which absorbed sister label MCA earlier that year. Critics generally complimented the new, more "mature" direction taken for the release and lead singles "Feeling This" and "I Miss You" charted high, with the latter becoming the group's second number one hit on the Billboard Modern Rock Tracks chart. Fans were split by the new direction, and tensions within the band—stemming from the grueling schedule and DeLonge's desire to spend more time with his family—started to become evident. He eventually expressed his desire to take a half-year respite from touring in order to spend more time with family. Hoppus and Barker protested his decision, which they felt was an overly long break. DeLonge did not blame his bandmates for being disappointed with his requests, but was dismayed that they seemingly did not understand. In addition, he protested the idea of Barker's reality television series, Meet the Barkers, which was being produced for a 2005 premiere. DeLonge disliked television cameras everywhere, feeling his personal privacy was invaded.

Following the 2004 Indian Ocean earthquake and tsunami, DeLonge agreed to perform at Music for Relief's Concert for South Asia, a benefit show to aid victims. Further arguments ensued during rehearsals, rooted in the band member's increasing paranoia and bitterness toward one another. He considered his bandmates priorities "mad, mad different", and the breakdown in communication led to heated exchanges, resulting in his exit from the group.

DeLonge's endorsement of John Kerry in the 2004 presidential election led to him travelling the political circuit with the Democratic Party candidate; DeLonge was inspired by Kerry's need for widespread reform and likened his presidential campaign to a drug, remarking later that it "really changed [me]". He rediscovered the epiphany developed during his tour with Kerry and applied it to the philosophy of his new group, Angels & Airwaves, while he redefined himself as he learned to play piano and self-produce and formed his own home studio.
