Miles Davis, Copenhagen Live 1969 (2LP; RSD Exclusive; 4400 copies)
Before Bitches Brew galvanized jazz audiences in 1970 and set Miles firmly on a new, electrified path, it was a well-kept secret but to audiences like this one at the Tivoli Koncertsal in Denmark on November 4, 1969, several months after the album had been recorded. An ensemble featuring Davis, Wayne Shorter on saxophone, Chick Corea on electric piano, bassist Dave Holland and Jack DeJohnette on drums – all key members of the Brew sessions – here preview about half the record with other material from the period in a crackling performance. This set, recorded by a film crew, debuted on DVD in the 2010 Legacy Edition of Bitches Brew and had an extremely limited vinyl release two years later alongside an book devoted to artist Mati Klarwein, who designed the original album cover and the surreal art herein.
