irty Sidewalks don't just take sonic cues from the fuzzy haze of The Jesus and Mary Chain, the honed pop songcraft of Oasis or the rich vocal colors of The Beach Boys-they keep it in the family, too. Formed in 2010 by Erik Foster, older brother Evan Foster (of The Boss Martians and currently The Sonics) and longtime friend Evan O'Neil, the band plays anthemic tunes.
