"Elvis Costello literally builds a band in front of the audience's eyes and ears. Joining him for this once-in-a-lifetime jam session are his former record producer, Nick Lowe, on bass; legendary New Orleans producer/pianist Allen Toussaint; U.K. guitar giant/songwriter Richard Thompson; and, from The Band, drummer Levon Helm."
