Earlier this year, five of the seven one-time or current members of Genesis came together in London to conduct interviews for a documentary on their career. Titled Sum of the Parts, it makes its U.S. debut tonight (Friday) at 8 ET/PT on Showtime.

In addition to one-on-one interviews, the film shows Peter Gabriel, Tony Banks, Mike Rutherford, Phil Collins and Steve Hackett being interviewed together and there is some riveting dialog between them, especially Gabriel and Banks with Banks saying how he did not like their last album with Gabriel, The Lamb Lies Down on Broadway. Also included is some rare footage, interviews with other members of the Genesis circle, including original guitarist Anthony Phillips, as well as a look at some of their solo efforts. This documentary is what led to the band’s recent compilation, R-Kive.
