Last Thursday night, Non Plus Ultra, a DIY art space in Virgil Village run by a group of L.A. artists, including members of the bands HOTT MT and Vinyl Williams, was buzzing as garage-rock stalwarts Thee Oh Sees were preparing to take the stage. There were about 350 people crawling around the space, which generally hosts crowds of about 150 or less – and the event attracted the attention of the City of Los Angeles Department of Building and Safety.
