Ralph Peterson-The Duality Perspective(2012)

Drummer Ralph Peterson did a strange thing to celebrate his fiftieth birthday. Instead of having a mid-life crisis and buying a Corvette, he put out an album that featured two distinctive bands, the only member of both bands being himself. The album is called The Duality Perspective, and the bands are his Sextet and a four-man group that Peterson has always called the "Fo'tet," instead of the common "Quartet."
