It's sex machine night at Bottom of the Hill. Blowfly — a funky, sensual superhero known for performing in nothing but a cape and briefs — is the wild-mannered alter ego of soul producer Clarence Reid, who beat 2 Live Crew to the punch by 25 years with his 1965 joint "Rapp Dirty." Distorted-country roughnecks Flexx Bronco might not seem the most natural openers for the slinky silver sensation, but their roadhouse riffs and foul mouths prove that a dirty mind knows no genre.
