History

Early years and formation (1983–1986)

The band was formed in early 1983 by two Peshawar University classmates, keyboardist Rohail Hyatt and bassist Shahzad Hassan, in Rawalpindi, Punjab Province of Pakistan, though no names of the band reached consensus. In 1983, the band started playing rock gigs at the local university campus, working with various unknown singers. The band came in contact with Jamshed after spotting him performing rock music gig in Peshawar University and Islamabad University campuses while as a student at UET in Lahore.

In 1986, Hyatt and Hassan officially formed the band after recruiting Nusrat Hussain as lead guitarist. The band began practicing by playing covers of Deep Purple, Eagles, Nazia and Zoheb, and Led Zeppelin in the early 1980s, and they made a name for themselves by playing in local five star hotels. As early as 1986–87, the band began looking for a lead vocalist, often going to local concerts to look for the singers. The band once again met with Junaid Jamshed after the band played with Jamshed at the Marriott hotel in Islamabad in 1987. Since 1983, Hyatt had wanted to recruit Jamshed as the band's lead singer, but was unable to do so when Jamshed left for Peshawar shortly. In 1987, Jamshed joined his engineering university's rock band, Nuts and Bolt, as a lead vocalist and performed at Flashman's Hotel in Rawalpindi. While Jamshed was performing, Nusrat Hussain, and Rohail Hyatt also went to the concert in search of new talent at the hotel. When Jamshed came to perform at the stage, Nusrat had tipped Hyatt off with a "that kid's coming back; the guy you liked" and that "perhaps we should go and see him." Hussain urged Hyatt to see him and after Jamshed's performance; they did and Junaid joined their band. A former band member Junaid Siddiqui was also added to the group to play drums for the hit music video "Dil Dil Pakistan."

At the concert, Hyatt patiently waited for the concert to be over as it stretched on until midnight. The show lasted till 3:00 am because people wouldn't leave, which was unheard of in Islamabad, where people packed up at 10:00pm. Junaid was immediately hired as the band's lead singer and got an offer for a show to open for a band called String Fellow. The promoter asked for a name of the band and during this time, the band had not reached an official name, just a group of four guys. Shahi attributes the name of band to when his older sister, who had just gone to medical university, told them: "This term of how you check the vital signs of life in a person". Hyatt immediately took the suggestion and named them "Vital Signs" for the first time since its formation. Various groups had garnered public attention, and rock music was appreciated as it was out of the ordinary.

Breakthrough era (1989–1991)

The success of their first single made Vital Signs much more popular, and they were soon discovered by famous PTV music producer and film director Shoaib Mansoor at the local concert, who was impressed with Vital Signs' "Do Pal Ka Jeevan" single. The next day, Mansoor called the band and asked them to do a national song which would go on-air all over the country.

Hum Tum (1995) and world tours

In 1994, the band did not extend the contract for its guitarist, Rizwan-ul-Haq, despite his urgings. Rizwan was relieved and "shown the door" after which Hyatt chose technical guitar whiz Aamir Zaki to become the band's new lead guitarist.

The Signs made its second tour to the United States with Zaki on board as the band's lead guitarist. Soon returning, the band started to work on their fourth and final installment, Hum Tum. Zaki was given the impression he was joining the band as a full member, not a session player, but was asked to leave after recording just three songs of the album. In a book, "Personal Biography" on Signs published online, Zaki had serious disagreement with the band leader, Hyatt, on the direction the band was taking.= Hyatt later stated that the predominant reason was because Aamir Zaki had criticized David Gilmour's guitar-playing while the band was touring the UK and attending a Pink Floyd concert. Hyatt famously quoted: "That's ridiculous! That's one person's (Aamir's) opinion. You don't fight or drop out of bands because of that." Following the departure of Zaki, the Signs quickly hired Awaz band member, Asad Ahmed, as the band's lead guitarist who would play at the UK concerts. In a turmoil situation, Hyatt soon left the Signs clashing with lead singer Junaid Jamshed and bassist Shahzad Hassan over a contractual obligation the band had for a series of concerts in the US, after Zaki joined the Signs for a US tour. Rohail Hyatt then also went on to start a music magazine called Vibes.

Upheaval and break-up in 1998

While on the US and UK tour, the Signs felt the need of Hyatt; therefore upon returning to Pakistan, the band quickly reconciled with Hyatt, and fired Zaki. Ahmad joined the band and played guitar for the rest of the pending album, with Hyatt on keyboards. For the fourth album, the Signs collaborated with Shoaib Mansoor; all of the songs were written by Mansoor and sung by Jamshed.

Though the band's demise was never officially announced, by 1998 when the Signs were offered a deal by Pepsi Pakistan Inc. for another album, Rohail declined, signaling the end of Vital Signs. Junaid Jamshed went on to pursue a career as a solo singer, and Shahzad Hasan concentrated on his work as a music producer with Rohail Hyatt who formed a production company, known as "Pyramid Productions".

The Vital Signs reunited for a 30-minute performance at the concert.

2013 collaboration

After 11 years, the members of Vital Signs and Junoon collaborated to release a patriotic song, Naya Pakistan. Written by Salman Ahmad and Aania Shah featuring Shahzad Hassan on bass guitar, Nusrat Hussain on keyboards, and vocalist Junaid Jamshed. The song was recorded at Indus Music World Studios and released on 22 February 2013.

Salman Ahmed while talking about his latest project at BBC Pakistan said, "For almost a decade, Junaid has always asked me not to bring guitar or to ask him to sing. When you are friends with somebody you always have to transcend differences and I respect Junaid's views. Junaid once told me that his biggest regret was not to be a part of Jazba Junoon's recording. So when we came up with "Naya Pakistan", I asked him that this is the chance that's not going to come again so finally Junaid accepted the offer with the condition that he will sing only the opening lines with no music at all."

Musical style

Vital Signs were most heavily influenced by Pink Floyd.

In a short span of time, the members of Vital Signs gained enormous popularity and were generally welcomed by the public; sometimes named the Beatles of Pakistan. Whilst Noor Jehan, Abida Parveen, Mehdi Hassan, Salma Agha, and Nusrat Fateh Ali Khan remained mostly attached to Pakistan's film industry, the Vital Signs reached out to the regional and young population of the country. According to the biographers of Vital Signs, despite the Western looks and influence of the Vital Signs, all of the members of Vital Signs were treated like country's most "beloved celebrities".
