It's a 4 step game and involves using image edting software as well as too much time on your hands:
1) Go to Wikipedia and click "random article" - that's your band's name.
2) Go to Wikiquote and click "random page" then pick a quote at random from that page - the last 3-5 words are your album title.
3) Go to flickr's "last 7 days" page (you might have to google search to find it) - the 5th pic is your album art.
4) Combine the results in photoshop, or whatever image editor you have, and post for all to see.
Here's one I prepared earlier. I don't know why but this genuinley made me laugh.
