I'm about to begin a small project creating a couple of short videos to help promote a outdoor festival I'm involved with. Now we all know that key to a good clip is a good tune. My question is what's a good way to source this? Obviously I intend to respect copyright. I can't imagine every clip I see online has been created with a music budget though. Is it a case of contacting small bands and asking for a favour? Because as an illustrator I know how annoying this can be when you're on the receiving end. Are there sites where you can source loyalty free music or what? Any advice or pointers would be very welcome.
