California Dreamin' at the Highline was a sea of 21 and 22-year-old loyal garage fans, most of whose clothing and bags bore one of Burger Records' oversized trademark buttons. (Someone there later told me they had stopped wearing their Burger button because it had started to feel kind of cult-like, but then also admitted they had met a ton of cool people just because wearing the button is a conversation starter for others who liked the same music).
When I got there, I hung out on the patio while the girls next to me sprayed down their black combat boots with cans of green and silver glitter spray-paint. I was content to sit out a few of the (eight!) bands before the local shredders in Big Eyes played, but as the first few songs of the Summer Twins filtered outside, their music immediately reminded me of both Cody Blanchard's surf-guitar playing in Shannon and the Clams and Shana Cleveland's girl-group vocals in La Luz, so I headed in to catch to rest of the set of glossy '60s retro-pop.
After looking into them a little more later on, I found out that they are a Burger band whose core members are sisters Chelsea (guitar, vocals) and Justine Brown (drums, vocals) from Riverside, CA, but they play shows and tour with an additional bassist and guitarist. I've been listening to their self-titled album non-stop since the show, and I highly recommend them for some lazy background music at the beach (it even sounds really great coming through crappy sand-lodged speakers of my portable beach stereo that have nicely survived the abuse of a few accidental dunkings.)
