The Sidekicks headline 16-band, outdoor affair in the CD102.5 Big Room Bar parking lot

A late addition to the summer festival lineup, Frontstage Fest packs 16 bands into a single day in the CD102.5 Big Room Bar parking lot on Saturday, Aug. 11.

Headliner the Sidekicks, playing behind the hook-laden, career-best Happiness Hours, is an obvious highlight, as is indie-rock quartet didi, which headlines Ace of Cups on Friday, Aug. 10, in support of the local release of its long-in-the-works new album, Like Memory Foam (expected out in wider release later this year on Damnably Records). But don't sleep on a deep undercard that includes bruising MCs (Sam Rothstein, JaySwifa), youthful skuzz-rockers (Radattack, far better than its name) and rarely sighted artists who tend to be can't-miss live (Nick Tolford). Best of all? Tickets are only $10.
