Documenting Miles Davis' 1969 "lost" third quintet live in Berlin, Stockholm and Rotterdam with Wayne Shorter, Chick Corea, Dave Holland and Jack DeJohnette, this 2-CD set captures the post-In a Silent Way ensemble reshaping material headed toward Bitches Brew, balancing lyricism and abstraction through open forms, electric-piano clusters, volatile rhythmic invention and Davis' fiercely exploratory trumpet.
