I participated in a press outreach campaign to funnel traffic to an infographic before, which resulted in over 1,000 Facebook likes for the graphic.

Identify the popular niche music websites (blogs, publications, video shows, radio shows, and MySpace), plan an event around your new album or concert tour, and then pitch the outlets one by one (introduce yourself appealing to commonality or social proof, and then dangle an exclusive coverage re: your event). You can pitch your friends to promote the event once the news have broke.

This is all I can think of with the given context. If you'd like, book a call with me and I'm happy to walk you through the strategy LIVE.
