The fact that the world of rock no longer objects to television causes the odd rheumatic knee twitch in people who grew up in the â90s indie orthodoxy. But that doesnât mean it hasnât had some positive cultural side effects. Consider the super-smart, weirdly excellent band Polarisâwhich was formed to make music for the Nickelodeon show The Adventures of Pete & Peteâwhose R.E.M./Pavement/ Velvet Undergroundâindex pop never had a chance of breaking through to the snobs who would have loved it. Theyâd almost definitely have fared far better today than they did in 1999, the year their only album came out. Or maybe bands like this need the cushion of posterity to be considered acceptable. Even though everyone likes to complain about how the internet killed obscurity, songs like the loose, downtown dirty âSummerbabyâ are legitimate lost classics, all the more precious because ânobody knows, nobody knowsâ them. Well, not nobody. If thereâs one thing the internet is good for, itâs reminding you that itâs never nobody. Polaris are back for the time being, on their first tour ever, tonight at the Crocodile. (And The Great Big Happy Green Moonface, their new "digital cassingle," is a bargain at $1.99.)
