I wish I did man. Schranz is kinda weird like that though, its huge in the european free party (free tekno) scene. Most of the artists would much rather play their music to the people who support the tekno scene then sell out or make a bukc off of it, hence why there are a shit load of white label schranz records.
peep these videos:

If your ever in europe you should check to see if there is going to be a teknival event, the majority of the music is speedcore, gabba, old hard acid, schranz, and from what I've gathered from the UK ones Hardstyle.
