A documentary drawn from a remarkable series of concerts of improvised music at London’s Café OTO. Filmed across four Saturday nights in July 2022 when over 30 musicians joined improviser, percussionist and animateur Eddie Prévost on stage for his 80th birthday residency. The film offers a candid look at improvisers who create music in the moment, free from the authority of a composer, score or conductor — culminating in the final ever concert by the pioneering group AMM.
