Beware sharks
Summer time always brings us back to Surfer Blood. The beachy alt-rock band, led by John Paul Pitts, made a splash (sorry) with the 2009 single “Swim” and their second album, “Pythons,” drops tomorrow — but all the cool kids have been listening to it on NPR First Listen for the past week to get excited for beach times. 8 p.m. at Rams Head Live. $25.

See, the Brits invented groovy
We are glad young people appear to have stolen all of their parents’ Curtis Mayfield records. It’s resulted in bands like English neo-soul band the Heavy. Playing South by Southwest in 2008 gave the band a boost in the U.S., as did major play in magazines like Spin. Funky horns and sweet grooves never go out of style. 8 p.m. at Sixth and I Historic Synagogue. $17.50.

The male Lady Gaga
Ariel Pink is a cartoon of a frontman, the quintessential stringy-haired rocker with whimsical shades and a penchant for using his armpits to make instrumental-sounding noises on his recordings. His freak folk is fun to dance to, though, and with the U Hall sound system his show should be a blast. 7 p.m. at U Street Music Hall. $20.
