Replying to The Vowel Movements mystery

I present you with a pickle that I am in: Many of you may be familiar with the hip hop group Vowel Movements from their song Escape (the jimmy buffet remix at the end of the credits in Ski Movie 3, "If you like green marijuana..."). I was able to get a few other songs by them on Kazaa such as Like Thata and Eligible Bachelors, and they are all great songs. When I tried to buy their album on Amazon (or anywhere for that matter), there is nothing there. I can't even find anything about the group when I google it. What's the deal? Is Vowel Movements just some weird collaboration thing that only released a few songs or something?
