Jennings formed
Acid Reign in 1985, along with Howard "H" Smith, Kevin "Kev" Papworth, Ian Gangwer and
Mark Ramsey Wharton, while attending
Harrogate High School (then-called "Granby"). After recording their debut EP, Jennings departed from the band in 1988, being replaced by
Adam Lehan. Then in 1989, Jennings was contacted by ex-
Napalm Death vocalist
Lee Dorian with the proposition of forming a band together, which would end up becoming
Cathedral, and would also include then-Acid Reign guitarist Adam Lehan. Cathedral would announce their breakup shortly after the release of their 2013 album
The Last Spire, leading to Jennings reforming Septic Tank, this time with Jaime "Gomez" Arellano, due to Barry Stern's death in 2005. ==Discography==
