If the legendary, mad Mardi Gras injuns of the Wild Tchoupitoulas have a 21st-century equivalent, it's Ivan Neville's Dumpstaphunk. Started in 2003 as a side project by the acclaimed keyboard player (and son of Aaron Neville), the band has become one of the fiercest, hardest funk bands on the festival circuit. Strutting second-line rhythms bump booty with funkadelic shakedowns, saxophone skronk and freestyle MC interjections in an urban shock-out that rocks like a hurricane and preaches a fiery gospel of inner-city solidarity and renewal. "Don't let them haters piss you off!" shouts Neville on the Family Stone-esque "Shake It Off." "We just need some space to breathe." And space to stretch the nastiest grooves across what remains and what will be of the New Orleans landscape.
