The second CD for the wittily named band the Nels Cline Singers, an instrumental outside-the-lines jazz group, arrives in the wake of Cline's enlistment as Wilco's go-to guitarist. With bandmates Devin Hoff on bass and Scott Amendola on drums, Cline launches into free-wheeling improvisation territory on "The Giant Pin" that is at once angular, sweet, bristling, assaultive and gripping. The trio rocks with crunch on "Fly Fly," smears and scratches with electronics through the melodic "He Still Carries a Torch for Her," paints an eerie soundscape on "Something About David H." with guest keyboardist Jon Brion dabbing in sonic color and muses with quiet beauty on "Watch Over Us."
