The Plastic People of the Universe - Egon Bondy's Happy Hearts Club Banned 1974

Sounding like a meeting between Zappa, Henry Cow, and Allen Ginsberg, this is a wild, politically-charged chunk of avant-garde agitprop. Egon Bondy's poetry may not be the most lyrical you've ever heard, but his imagery is striking in its desperation and anger. Lots of honking saxes courtesy of Vratislav Brabenec, who is a big-time blower in the style of German free jazz player Peter Brotzmann. For those whose love for the late-'60s/early-'70s progressive rock is boundless, this is absolutely essential. But, even if you're squeamish about anything labeled art-rock, don't pass this by; the raw emotions and intense idealism in the face of oppression, despite their being sung in a language you don't speak (there are English lyrics on the LP jacket), are very moving.
