Restocked, reduced price. 2CD Edition. In 1968 Mainstream released an LP with AMM on one side and MEV (Musica Electronica Viva, then based in Italy) on the other. In 2004 the two groups re-convened in London. Two of the five original AMM (Eddie Prevost and Keith Rowe), and three of the original five MEV (Alvin Curran, Frederick Rzewski and Richard Teitelbaum) still in place. The only new boy on this CD is their contemporary John Tilbury; since 1980 he has been the stable third AMMusician. On CD 1 the entire ensemble is in a studio, in meditative mood mostly; on CD 2 the two groups play separately at the 'Freedom of the City' festival in London the following day - a very good live recording, and a rare opportunity to hear MEV again. It was a great concert. IIlustrated booklet with a substantial essay by Harry Gilonis.
