A really great idea for a collection – one that brings together postwar modern music in all of its many formats – from avant jazz, to early electronics, to Indian music, 20th Century classical, and even a bit of straighter jazz moments too! The package is very ear-opening – as it offers the chance to hear instrumentalists next to compositional talents that had inspired them – and the collection provides a way to hear different strains of sonic experimentation that were sometimes running parallel to each other, sometimes criss-crossing in strange ways. There's a wealth of musical discoveries throughout – and the 4CD set is overflowing with key cuts from Ornette Coleman, Bela Bartok, Edgard Varese, Daphne Oram, Jean Sibelius, Eric Dolphy, Ravi Shankar, Pierre Henry, John Cate, John Coltrane, Humphrey Searle, Arnold Schoenberg, Bill Evans, Olivier Messiaen, Luigi Nono, Charles Ives, Karlheinz Stockhausen, Bruno Maderna, Julian Bream, and many others.
