A visual cross between the leather bondage movie “Cruising” and the raunchy retro-fuelled imagery of early John Waters movies like “Desperate Living,” San Francisco’s queer Hunx and his Punx (one of whom is Seth Bogart of former Gravy Train!!!!) have injected humor, imagination and fun into their prodigious multimedia output, which includes records and videos. Hunx’s bouncy pop sound is equally cool, melding ‘60s-based bubblegum pop sensibilities with DIY garage prowess for a sticky-sweet aural assault.
