Activate is the fourth studio album by Back Door, released in 1976 by Warner Bros. Records.[1] It was produced by Carl Palmer, known for his drumming in the bands Atomic Rooster and ELP. Original member Tony Hicks had left the band before recording the album and had been replaced by Adrian Tilbrook on drums. After the release of Activate, the band played less and less together, and eventually broke up around 1977.[2]
All tracks are written by Ron Aspery and Colin Hodgkinson, except "Thru the Zig Zag Gate", "Train Won't Blow" and "Eliminate" co-written with Adrian Tilbrook.
