Active between 1988 and 1994, SyKotic Sinfoney was a short lived, but highly original band with the kind of sound I'm just a sucker for. It's a real shame they band didn't do more. Other than the Bad Channels soundtrack, and their amazing appearance in the film, plus a handful of self releases; there isn't much to find. But boy oh boy, is Manic Depresso worth finding! And being released in 1992, it was before most of the masked whacky bands and close to the same time as Mr. Bungle.
After a bit of searching, I was able to locate an official website found here! There you can find some more information and a shop with their full length album and several live DVDs. Not sure how long its been since it has been updated though.
