These days, veteran folk-rocker David Crosby is more notorious for talking shit on Twitter than for making music. But Crosby is in an uncommonly productive period, making three albums in the past four years. And now, as NPR points out, he’s getting ready to follow up last year’s Lighthouse with a new LP called Sky Trails. First single “Sell Me A Diamond” is a jazz-flecked meditation on trying to buy a conflict-free piece of jewelry. Check it out below.

Sky Trails is out 9/29 on BMG.
