The Dirty Heads A mix of acoustic folk, hip-hop and reggae, the Dirty Heads’ vibe can take awhile to soak in. Channeling a surfer and stoner dude aura, with a pervasive reggae undertone in most songs, they’re still a bit raw and testing musical waters. Guitar god Slash lends his screaming six strings to their track “Check the Level.” Also on the bill are New Politics and Bums Lie. $13-$15. Amos’ Southend. www.amossouthend.com. (Samir Shukla)

David Liebe Hart It’s hard to know whether singer/musician/ventriloquist David Liebe Hart is crazy — or a damned genius. On one hand, the guy managed to make the jump from struggling/street artist/public access TV show host to a steady singer/comedian role on the Cartoon Network’s hit program Tim & Eric Awesome Show Great Job. That exposure allowed him to tour the nation, performing his bizarre original songs with fellow musician Adam Papagan. But, on the other hand, the dude is totally convinced he was abducted by aliens — going so far as to claim that he’s had romantic liaisons with extra-terrestrials. He even sings about off-worlders (like on his trademarked song “Salame.”) That said, the guy’s got waaayyy more money and fame than me ... so maybe he’s the lunatic we’re all looking for. With Hunx and His Punx, Shannon and the Clams, The ‘97 Bulls. $10. The Milestone. www.themilestoneclub.com. (Carlton Hargro)
