Formed in 1983, Possessed were an early and heavily proficient thrash/death/black/crossover/etc. metal combo from the San Francisco Bay area. Initial membership shakeups eventually lead to this line-up: Mike Torrao - guitar, Larry LaLonde - guitar, Jeff Becerra - vocals + bass and Mike Sus - drums; which put out three releases - Seven Churches (1985), Beyond the Gates (1986) and The Eyes of Horror (EP) (1987). Their sound moved from Satanic themed hyper-fast death brutality towards a more thrash infused style.
After Possessed broke up, guitarist Larry LaLonde joined San Francisco metal band Blind Illusion in 1988. Soon after in 1989 he and Blind Illusion's bass player, Les Claypool, started up long running funk metal act Primus.
Here's some footage of Possessed playing Baltimore in 1987.
