On January 29 Columbia/Legacy released the remarkable second installment of its Miles Davis “Bootleg Series,” Live in Europe 1969. It’s a weighty item containing three CDs and a DVD of live performances by a lineup of the band that never made a studio recording; these performances were taped by various European state-owned media outlets and some of the music has surfaced previously as second-rate bootlegs, but the recordings have been cleaned up nicely here. Saxophonist Wayne Shorter was near the end of his stint with the band—which began in 1964 and ended in 1970—and keyboardist Chick Corea, bassist Dave Holland, and drummer Jack DeJohnette were all relatively green entrants into the fold, and there’s no question this massive document captures a band in the midst of an exciting transition.
