Whatcha doin’ Saturday night? You could punish your eardrums with bands like Doom Siren and Disempower at the Broken Neck, enjoy the Scoot Inn’s Coney Island Fest (which, with any luck, will serve up those delicious mid-west morsels they call coney dogs), or you could step into a Valium haze with those country-echo pioneers The Cowboy Junkies at The One World Theater. But to experience some raw rock’n’roll, you might be better off treading down to Emo’s Lounge, where the only thing to separate you from the noise is that weird split level moat-thing....
