Really, anyone can do crazy stuff with Unbound, including some kick butt progressive. If you don't know what progressive is, just think of it as alt quirk with flings.
Anyways, guys, if you're going to be in, have as little airtime as possible. That's what makes a track stupid and uninteresting. Too much time between tricks makes the track boring, unless the tricks are absolutely amazing.
I'm going to have to approve you, because I just can't take everyone that signs up. I assure you there's a good chance of getting in. To sign up I'll have you present a track to tell your skill, or a recording of something new(recommended). For a more accurate decision, you should make a track about 10 seconds, upload it to whatever's convenient, and add a link to the recording so I can assess your skill level. I'm not going to respond saying you're in. Don't ask why; I have my reasons. I will, however, add you to the list of participants in the collab.
I'll start out with 3 slots, and if this gets popular I'll add more.
