This Australian’s 2004 album, Grapes From the Estate, took the mighty drone metal associated with Sunn 0))) (who Ambarchi sometimes joins on stage) and turned down the volume, creating bucolic, ambient soundscapes drenched in sustained notes as rich and viscous as honey. Now he’s at it again, adding piano, strings, bells, shimmering percussion, and even a few (incomprehensible) vocals to three new tracks. He drops one speaker-vibrating note after another, then lets the tones swell and ripen while laying down a few melodies. The result is somewhat darker than the last outing, but overall is pretty much the same. Does that mean we’re fed up? Not at all! After music this good, we’re ready for thirds.
