Kamasi Washington's soundtrack to Becoming, the Michelle Obama Netflix documentary, is just what you might expect from the talented saxophonist and the subject matter: classy and uplifting smooth jazz. The title track is soulful with a little retro swing and "The Rhythm Changes" is lightly funky, like the theme song for a smart '70s TV series. "Provocation" stands out for its ominous, dramatic chords and flurrying swells, but the highlights here might be "Southside V.1" and "V.2." The related tracks will put a smile on your face with their feelgood optimism. Remember "Hope"?
