Considered by many to be the original rapper, since the early ’70s Blowfly has been delivering sex-based song parodies and original dirty ditties (95 percent of which we surely can’t print!) like “Blowfly’s Rapp” and “Nobody’s Butt But Yours, Babe” to an audience hungry for his blend of R&B, soul, funk and filth – all while clad as a superhero in mask and cap. The now-75-year-old Blowfly hits town; his gig this weekend features heavyweight openers Twinki, Tough Junkie and Heavy Flow.
