I have seen a whole lot of one- and two- man bands on YouTube lately. It can be difficult not only to find musicians who are capable of playing the same things you can but who want to. A lot of these cats use drum machines but at least one of them played all the instruments himself. That is the way a lot of famous musicians started out, you know. (Well, a handful of them, including Prince.)
Whether you are involved in one of these situations or just want a williams 88-key digital piano to rock-out on, follow this link to check it out. You might need to program it as accompaniment or just want to play it with your band.
