There is a paradox that while the Peter Gabriel era of Genesis was undoubtedly their most inspired, their best album was A Trick of the Tail, which was their first post-Gabriel's departure.
My opinion, anyway.
The first track of which was "Dance on a volcano". Can't think why it's been on my mind over the last day or so. Dual drumkits, everyone with long hair, Mike Rutherford almost dwarfed by his double-necked guitar ... It's the seventies!
