Tucked away on a downtown block of concrete nothing, just a few strides from the baby Brooklyn vibes of the Arts District, Lot 613 occupies a unique space in the landscape of Los Angeles clubbing. It has the aesthetic of a renegade warehouse –– a stripped-down, industrial cave with few frills –– but is fully licensed and legal, and often stays open until 4 a.m. It is the home base of Prototype, a party series that consistently features the best underground dance bookings in the city — Âme, Nina Kraviz and local legend DJ Harvey have graced 613's unadorned decks in the past few months alone. Its massive outside area, replete with full bar and taco operation, provides needed respite from the booming bass and heaving bodies of Lot 613's shadowy inner den, where you'll find a much wider demographic of Angeleno hip kids getting down than at any Hollywood club. While L.A. nightlife has a somewhat deserved reputation for flashy materialism, Lot 613 is about the music and nothing else.
