Query: Jazz is heat

Jazz is this, jazz is that. Madlib'sShades of Bluewas an ingenuous reimagination of these classic tracks, some sampled heavily, some not so much. Madlib's treatment of the tracks are so varied that you almost can't tell how much his hands are on them. This record proves that it doesn't take much to make these tracks always enjoyable.Yet how could they not be? These are all-star lists of session musicians and radical concepts. "Montara" creeps along at a sensual pace, "Shades of Slim" retains its fluid, funky vibe in the forty years since it was released, and "Mystic Brew" (a track that is sampled to death, for good reason), sounds better than ever before.Good call on Blue Note to allow Madlib into the vaults. A great call by allowing the tracks to be rereleased, in their entirety, and enjoyed for the young jazz fans who could never find these records. I know I had my share of troubles. Now they're gone.
