55 Cadillac is the instrumental solo piano album by Andrew W.K., released in 2009 through Ecstatic Peace! (vinyl only) and W.K.'s own record label, Skyscraper Music Maker. The album features "new-age" spontaneous solo piano improvisations and was recorded in Cleveland, Ohio.
Writing about the album's release in The Guardian, Andrew WK said, "I wanted this new 55 CADILLAC album to sound like freedom. The sound of a piano being played by a free man – nothing more, nothing less. This was the first chance in almost 10 years where I was allowed to simply play and record an instrument – no songwriters, no lyrics to learn, no overdubs, no slow fixes, no remixes, no video shoots or interview practice – just the sound of someone sitting in room playing piano for the sake of it. No one telling me what to play, or how to play it. And no masterplans, high-concept visions, worldwide goals with roll-out schedules. No style consultants or acting coaches. No more meetings with sponsors or computerized yelling. No more threats."
