The 2nd volume of the UK/US West Coast quintet of legendary AMM drummer Eddie Prévost, guitarist Henry Kaiser, N.O. Moore on "guitarisism", Blinker Golding on saxophone and Olie Brice on double bass, merging free jazz and free improvisation in a rollicking album of electric jazz recorded in London, adding two more exhilarating "Doors" of quick shifting improv.

A series of impressive improvised solo drum performances by AMM/Matchless leader Eddie Prévost performed at Network Theatre in London, 2012, three pieces with each demonstrating a different characteristic of his remarkably creative and technically virtuosic playing, first with drum sticks, then with "Hands, brush, hands", and finally "Sticking it too".

Their 1st album released in 1977 on Spotlite Records label, the free jazz quartet led by PrŽvost on drums, Geoff Hawkins on tenor saxophone, Gerry Gold on trumpet & flugelhorn, and Marcio Mattos on double bass, released two live albums on the Matchless label before disbanding; this live album from Cata OTO in London in 2020 reunites the band for a solid concert 42 years after.

Percussionist, Improviser and AMM founding member Eddie Prévost's fourth book presents a fascinating series of reflections and challenging insights on music in its various forms, and the development of improvised music at the intersection of contemporary compositional and conceptual forms; alongside a personal history of Prevost's life and his relationship with music.
