This week on Adventures In Sound And Music writer, thinker, listener, musician and longterm associate of The Wire David Toop joins Derek Walmsley to discuss improvisation and his long awaited book Into The Maelstrom. This first in a projected two-part history examining the rise of free music in Europe and beyond outlines its genesis in such disparate movements as dada, experiments in post-bop, postwar art, modernist literature, Japanese gakaku, live electronics, free rock and more. David will be in the studio to play rare recordings, talk about his book, and to improvise a discussion about improvisation.

Adventures In Sound And Music will air on Thursday 9pm. Tune in on London 104.4FM or stream at resonancefm.com
