Following his departure from Rainbow in 1980, Graham Bonnet carried on his musical journey. In 1981 he recorded his fourth solo album (‘Line Up’) and in 1982 replaced Gary Barden as the voice of the Michael Schenker Group. In 1983, Bonnet joined Alcatrazz, with whom he recorded three albums. Their 1985 disc ‘Disturbing The Peace’ (featuring Steve Vai) ranks alongside Rainbow’s ‘Down To Earth’ as a career high point for the prolific vocalist. After brief stints providing vocals for Forcefield (a band featuring his old Rainbow mate Cozy Powell), Pretty Maids and Chris Impelliteri, he landed a job in 1991 as the frontman for an all-star rock band named Blackthorne.
