Nat Baldwin’s alt cred is impeccable. Not only is he a former bassist for Brooklyn’s über-cool Dirty Projectors, he’s also responsible for a string of releases that began with 2003’s free jazz set Solo Contrabass. Also prepared to take a stroll with the less cool, he’s been heard on a TV ad for Orange mobile phones, the one with the barefoot, ladder-descending lady. Although People Changes worms intimately in, it’s hard to detect a singular voice. Formerly in thrall to Anthony Braxton, he’s now trying on Arthur Russell.
