Potter took home the New Groove Jammy in 2006 and performed with an eclectic cast that included Joe Satriani, Steve Kimock, Jane’s Addictions Stephen Perkins, Willy Waldman and Jacob Fred Jazz Odyssey bassist Reed Mathis. Haynes and Potter have performed together a handful of times recently, often collaborating on lauded classic-rock covers.
