Production is finished and now the US producer asks me to send the music clearance forms....? I know these in Holland, but not in the US Does anybody has an idea of where to get these forms, are they standard? should i make something up?
You can ask the MU for clearance forms - give them a call and they'll be very helpful. That is, of course, if you paid MU rates!
If you're not talking about musicians for a session, you'll need clearance from whatever record label you have cleared the music with - it'll be a synchronisation & master usage license.
