As Mute Duo, pedal steel guitarist Sam Wagster and percussionist Skyler Rowe drift and rage with unusual grace. Best known for collaborations with Ryley Walker, Bill MacKay, Ben Lamar Gay, and Tim Kinsella, the two players stretch out gloriously on their latest, Lapse in Passage, which twists and churns within the heady post-everything frame work that has flourished in their hometown of Chicago, evoking loose-limbed spiritual jazz, inverted exotica, and ragged improv.
