The aptly named Free Energy is bringing their guitar-driven power pop to the North Star Bar tonight. With upbeat rock that makes you want to groove, the band has toured with the likes of Mates of State and Weezer, now in support their latest LP Love Sign, which was released earlier this year via the group’s own label. There’s something about Free Energy’s carefree lyrics and punchy guitar riffs that make the music so much fun and perfect for this gorgeous weather. It doesn’t hurt that they know the cure for rock ‘n’ roll fever is more cowbell. Also featured is the LA-based duo Deap Vally, who Free Energy have been roaming the landscape of America with. These two ladies have their own energy to share with their grungy, blues rock ensuring the night to be a rollicking good time. Also ready to help the crowd freak out will be locals Prowler. North Star Bar, 2369 Poplar St., 9pm, $12, 21+ – Shaylin O’Connell
