Medeski Martin & Wood, Robert Randolph & the Family Band, Galactic, Widespread Panic, Jam Underground, Diazpora, Soulive, and Karl Denson's Tiny Universe all drew heavily from the funk tradition. Lettuce, a band of Berklee College Of Music graduates, was formed in the late 1990s as a pure-funk emergence was being felt through the jam band scene. Many members of the band including keyboardist Neal Evans went on to other projects such as Soulive or the Sam Kininger Band. Dumpstaphunk builds upon the New Orleans tradition of funk, with their gritty, low-ended grooves and soulful four-part vocals. Formed in 2003 to perform at the New Orleans Jazz & Heritage Festival, the band features keyboardist Ivan Neville and guitarist Ian Neville of the famous Neville family, with two bass players and female funk drummer Nikki Glaspie (formerly of Beyoncé Knowles's world touring band, as well as the Sam Kininger Band), who joined the group in 2011.
