“It’s a movement, rather than a festival,” says LA hotelier Stefan Ashkenazy of the Bombay Beach Biennale, the event he founded to regenerate a Southern Californian ghost town. The landlocked Salton Sea went from vacationers’ playground to apocalyptic movie set when its polluted waters started retreating in the 1960s. Now an influx of creative types is striving to restore visitors and vitality to this stark desert landscape. This ironically named “biennale” – the antithesis of Venice’s slick art-fest – is so under-the-radar that exact dates are only announced at the last minute. Still, Bombay Beach draws visitors year-round for permanent installations such as a drive-in filled with burnt-out classic cars, a prank “art museum” by Greg Haberny that recalls UK street artist Banksy’s dystopian “bemusement park” Dismaland as well as Tesseract by self-taught abstract metal sculptor Steve Shigley.
