Electro-funk duo Big Gigantic have teamed up with fellow sax-wielding funk icon GRiZ for a brand new collaboration, which comes to their fans free of charge. "Good Times Roll" supplies just what you might expect from a collaboration from them — funkdified beats complete with smooth saxophone progressions and the kind of head-nodding energy necessary to move festival crowds. This All Good Records release is one you can expect to hear at Big G's two-night return of Rowdytown at Morrison, Colorado’s Red Rocks Amphitheater, which will also feature RL GrimeThomas JackJauzSnails and more as support between September 25 and 26.
