In the late 1980s and early 1990s, there was a boom in rave culture in the San Francisco Bay Area. At first, small underground parties sprung up all over the SOMA district in vacant warehouses, loft spaces, and clubs. The no alcohol rule fueled the ecstasy-driven parties. Small underground raves were just starting out and expanding beyond SF to include the East Bay, the South Bay area including San Jose, Santa Clara, and Santa Cruz beaches. In late 1991, raves started to expand across northern California, and cities like Sacramento, Oakland, Silicon Valley (Palo Alto, San Jose). The massive parties were taking place in outdoor fields, airplane hangars and hilltops that surround the valley. San Francisco's early promoters and DJs were from the UK and Europe. Raves took place in some of the SOMA art museum event such as, 'Where the wild things are' in the museum on top of the Sony Metreon, and in the Maritime hall (1998–2002). By the end of 1994, a new generation of ravers were attracted by the new sounds. EDM began to become popular. Raves could be found in many different kinds of venues, as opposed to just basements and warehouses. Promoters started to take notice and put together the massives of the late 1990s with many music forms under one roof for 12-hour events. Until 2003, the raves scene continued to grow slow and stay stable until there was increasingly awareness and publicity about illicit drug usage at raves, particularly ecstasy. Parallel to the rave scene growth, was an increase in anti drug policies, which were directly aimed and indirectly influenced rave organizational management and event. On 30 April 2003, the US Congress passed the Illicit Drug Anti-Proliferation Act, which has origins from a similarly purposed, but not passed, 2002 bill. That bill is notibily named The RAVE Act. Consequentially, by mid 2000s and late 2000s larger raves appeared more sporadically. Nevertheless, and parallel to new city ordinances regarding curfews and drug enforcement, rave event promoter companies like Go ventures and Insomniac persisted and continued annual scheduled rave events like Monster Massive, Together as One, and Electric Daisy Carnival. From this base of routine and consistency scheduled events, the rave scene reemerged with in 2010 with even more attendance and dance locations. The overwhelming attendance, including from lack of underage attendance restrictions, reached a changing point with the 185,000 estimated in attendance 2010 Electric Daisy Carnival (EDC).
