The Ian Gillan Band were an English progressive jazz-rock band formed by singer Ian Gillan of Deep Purple in 1975. Their sound is a departure from the heavy metal of Deep Purple by featuring a progressive jazz fusion sound, more similar to bands such as Brand X.
History
After leaving Deep Purple in June 1973, Ian Gillan had retired from the music business to pursue other business ventures, including motorcycle engines, a country hotel / restaurant (with a guitar shaped swimming pool), and ownership of the Kingsway Recorders studio, where from April 1974 he began to work on his first post-Deep Purple solo tracks.
