1+1 is a 1972 album by Grin, featuring songs by their guitarist Nils Lofgren. As well as being an album in its own right, this was released by CBS in the UK as part of a 1976 double album set along with its predecessor Grin. The original LP was a gatefold. It had a photo of Nils on the front, with Bob & Bob on the back. The inside features triple exposure photos of the band members performing, giving the impression of motion. The sides are not labelled 1 and 2; instead, the first side is labelled "Rockin' Side" while the other is "Dreamy Side".
