The State assemblywoman, whose district includes the Daly City home of the Cow Palace, has introduced legislation to ban those all-night bamp-bamp dance parties from public land across the state. Unsurprisingly, it's called the Anti-Raves Act of 2011 and it seeks to ban any "public event at night that includes prerecorded music and lasts more than three and one-half hours.".
Ma doesn't want to infringe on bars or other licensed concert venues, so there's an exception for those, but as the Weekly's All Shook Down points out music festivals like Treasure Island and Outside Lands were both held on public land and included sections with pre-recorded music. According to the Examiner, Sean Manchester, owner of electro-friendly club Mighty and president of the California Music and Culture Association, is also concerned that the ban could affect events like street festivals in San Francisco. That said, Ma is soliciting input on her proposal, which is clearly going to need a couple rounds of revised language.
