Chemical Brothers perform at the Portola Music Festival in San Francisco on Sunday, Sept.

A pounding bass — boom, boom, boom — could be heard in parts of San Francisco and the East Bay over the weekend during the two-day Portola Festival at Pier 80 in Bayview, where top electronic music acts such as Flume, the Chemical Brothers and Fatboy Slim performed. .

Mark Schulze of Alameda told SFGATE that at times, the music was so loud that the windows in his home rattled.  .
