Sing No Evil

"Twenty-something guitarist Aksel stutters when he sings, and the latest reviews say he has the voice of a crow with throat plague. That's not a compliment, even for the avant-garde music his band Perkeros plays. Aksel is having a hard time keeping the band together, stopping his girlfriend from kicking him out, and not getting eaten by his drummer (who happens to be a cranky brown bear). There are also the rival bands that Perkeros find themselves in battle with to save the city from supernatural forces set loose by ancient music. The key to it all could be in the music Aksel hears in his dreams - if it doesn't drive him mad first."
