Doing exactly what it says on the tin, this album is a live jam of Prince playing his piano in the studio.
Recorded all in one take, he hurtles through nine songs without pause in just over half an hour, mixing up styles, moods and genres. He's freewheelin', playful and trying songs on for size, seemingly playing whatever pops into his mind.
Snippets of what would become classics fleet past as he breezes through material, his own and others, songs well known and previously unheard. When he really gets going he augments the tracks with sung "doof, doof, doof" drum fills in places that he'll later place his recognisable electronic drums when readying them for release.
In many respects, you can liken this to the pages of an artist's sketchbook. The date stamp of the recording proving the songs are works in progress and he's still figuring out what he ultimately wants them to be.
He opens with 17 Days, the song that a year later would surface on the flip of When Doves Cry, making it easily his most famous b-side. Performed on piano it's a far cry from the heavy electro funk most listeners will recognise.
