In 1986, the band's set at the Montreux Jazz Festival in Montreux, Switzerland, was recorded and released as "Mardi Gras at Montreux" on Rounder Records. The album and the band's touring successes attracted major-label attention, and in 1987 the band signed a contract with Columbia. Their Columbia debut, 1987's "Voodoo", featured guest appearances by Dr. John, Dizzy Gillespie, and Branford Marsalis. Later recordings saw them joined by a variety of special guests including Elvis Costello, DJ Logic, Norah Jones, and the man who started it all, Danny Barker. The group has also toured and recorded with jam band Widespread Panic, as well as spending almost all of 1995 as the opening act for The Black Crowes 'Amorica Or Bust' US Tour.
