Although it's not the reunion tour that fans of progressive rock legends Genesis have been hoping for, the band just revealed that they have been working on a big new project together.

Keyboardist Tony Banks shared a new picture of the group's famous 1971-75 lineup on his Facebook page, while also divulging that the band has been working in conjunction with the BBC to produce their first-ever documentary, 'Genesis: Together and Apart.' This marks the first time that this beloved version of Genesis - Tony Banks, Peter Gabriel, Phil Collins, Mike Rutherford and Steve Hackett - have been together since 1975.

'Genesis: Together and Apart' will offer a unique perspective into not only one of the most successful bands in rock history, but one of the most musically adventurous as well. From their start as a group of songwriters through theatrical progressive rock, jazzy pop and their final incarnation as chart-topping pop superstars, the documentary will focus on the band's ever-evolving songwriting. It will also offer a glimpse of previously unseen and rare performance footage taken from throughout their career.

A release date for 'Genesis: Together and Apart' has not yet been confirmed.
