If you follow the metal family tree back far enough, you'll probably come across Death Angel. The group formed in San Francisco in 1982 and became a vital part of the important Bay Area thrash metal scene — along with Exodus, Testament, and Metallica (after it moved to the area in '83). Death Angel toured hard and heavy throughout the 80's and released three studio albums, but come 1991, the band hit the brakes. The band reunited in 2001 and has been back in the groove. Death Angel released its seventh studio album, "The Dream Calls for Blood," in 2013 and is now working on new material for its follow-up.
Death Angel plays with Corrosion of Conformity, Age of Shadows, Armageddon, and Iconoclast on Saturday, April 18, at Montage Music Hall, 50 Chestnut Street. 8:30 p.m. $15. ticketfly.com; deathangel.us.
