There are more than one band called Angst:
1. Angst was an American punk rock band from San Francisco, California, formed in 1980 by brothers Joseph Pope, Jon E. Risk, and drummer Michael Hursey (later replaced by Andy Kaps).
Though Angst played many venues with a wide variety of bands, the majority of their shows locally were within the punk/hardcore scene. Their eclectic mix of punk, country, pop, 60s garage, etc. was not particularly well-received by the strict hardcore audiences of early ‘80s San Francisco. Read more on Last.fm
