With 2 or 3 people collaborating you can get a nice dynamic, sometimes, with the right combination of personalities.
But loads of people making one track?
It would end up getting homogenised.

Although maybe putting together a double ep or a CD compilation would be a good idea.
But seeing as the Blackout Audio name is marks, then really it would be something he would have to be cool with.

However, a CD compilation of the best of BOA, might be cool.
