From the never-predictable El label comes this excellent compilation of avantgarde performers from post-war Europe, featuring such legendary names as Karlheinz Stockhausen, Iannis Xenakis, Pierre Schaeffer, Pierre Henry and Edgar Varese. Not just for classical buffs, these names have proven to be a huge influence on the likes of Frank Zappa, the Beatles, Miles Davis, Can and a host of avantrockers, and these impossibly rare recordings make for an ideal introduction.
