For years the Society for the Activation of Social Space Through Art and Sound (SASSAS) has been deliberately blurring the lines among art, performance, sound, architecture, conceptualism and experience. This year they are building on the blur, with the launch of the SASSAS Records limited-edition series of vinyl LPs pairing previously unreleased music with artist-designed covers (for example, Nels Cline/Sterling Ruby). Their annual Blast! DJ Battle fundraiser is coming up May 31, and in anticipation of its silent-auction component, 1301PE Gallery hosts the Bootleg LP Art Auction Pop-Up Preview, on view May 27-30, with an artists’ reception May 28. The exhibit features some 60 of L.A.’s most adventurous visual artists, contributing original works inspired by their favorite album covers.
