So this album is a real underated gem. It was lost in the sea of dross that was Wings and McCartney's 70s output and a little too weird and out there for normal Beatles fans.
It basically comprises McCartney pissing about with a bunch of new synthesisers and recording equipment and in a weird way manages to prefigure acid, electro & post rock. Temporary Secretary became quite well known when Radioslave did a (shit) edit but there's a bunch of other great songs on the album.
