remembering HEATHEN bassist Michael Jastremski (1963-2005)

Mike Jastremski (March 16, 1963 - May 23, 2005)

Mike "Yaz" Jastremski was an American metal musician best known for his work as a guitarist and bassist during the 1980s Bay Area metal movement. The Metal Archives shows that Mike began his recording career as a guitarist for the speed metal band Griffin, performing with the group from 1983 to 1986. Under the moniker "Yaz," he recorded guitars for the band's 1984 debut full-length album, Flight of the Griffin. After Griffin, he switched to bass and joined the thrash metal band Heathen, serving his first tenure from 1986 to 1988. He performed on the 1987 single "Set Me Free" (cover song) and Heathen's celebrated 1987 debut full-length album, Breaking the Silence. In 1988 he also recorded a demo with the band during the brief period when former Exodus vocalist Paul Baloff fronted the group. Mike rejoined Heathen for a second tenure from 2001 to 2004. His bass work during his time with the band has been featured on several retrospective releases, including the 2004 compilation Recovered and the 2017 compilation Pray for Death (The Complete Demo Collection), which featured his bass tracks on tracks 8 and 9.
