Oh, Andrew W.K., what the holy fuck are you talking about? A-dubs recently recorded an album of short improvised piano pieces about a car, called 55CADILAC; here he is discussing it on the Guardian UK's music blog:

Over the past 10 years, I've had personal and professional issues with several people involved in my career, and due to formal agreements, I'm partially forbidden from going into detail regarding certain aspects of my recent work and, as a result, the making of the 55 CADILLAC album.

Here's what I am able to say: At the end of 2004, an old friend of mind got in some business trouble and basically decided to take it out on me. To cut a long story short, this person is someone I worked very closely with and had a formal and family business relationship with. Due to various complaints this person had with me, they were able to turn my life and career upside down. I wasn't allowed to use my own name within certain areas of the US entertainment industry and we were in a debate about who owned the rights to my image, and who should get credit for "inventing" it. This made my life complicated and intense for a few years, but I kept working and doing whatever I could to keep moving forward.

You'll recall Andrew WK (OR WAS IT?1?!) caught Line Out's attention a couple years ago thanks to a really bizarre performance at Chop Suey and some dispute as to whether or not he had hired an impersonator to perform in his stead. Unravel that whole mess here, here, here, and here.
