By all accounts, San Francisco's Blackhawk nightclub was a complete dive, but it had exceptionally good acoustics and an owner who didn't mess with the hired talent, which made it a reasonable recording site for Cal Tjader, Gerry Mulligan and, of course, Miles Davis, who cut this legendary recording in 61. At the time, Davis was backed by his famous Quintet (Hank Mobley, Wynton Kelly, Paul Chambers and Jimmy Cobb). As this four-disc set covering each standard-heavy set of a two-night stand demonstrates, this Davis band was really built for crowd-pleasing. The performances range from hard-swinging to beautifully tender, yet even in the quiet moments they're never less than intense. Fabulous.
