An important audio-visual record of a landmark series of four concerts staged in London in 2022 when more than 30 musicians joined improviser, percussionist and animateur Eddie Prévost to mark his 80th birthday. The film takes a close look at improvisers who create music in the moment, free from the authority of a composer, score or conductor. Ranging from profound delicacy to subversive atonality, the “awkward wealth” of this music raises vital questions about artistic freedom, individual responsibility and what it means for people to make music together in the 21st Century. Featuring performances by John Butcher, Sue Lynch, Ute Kanngiesser, Marjolaine Charbin, Nathan Moore, Seymour Wright, Veryan Weston, Alan Wilkinson, John Tilbury and Eddie Prévost amongst others. Plus readings by musician and author David Toop. The film includes the last ever concert by AMM, the pioneering improvising group co-founded by Eddie Prévost in the mid-1960s.
