It's hard to take musicians and their causes seriously -- are any of those Live Aid guys still aiding, or even live? For a virtuous music venue with legit cause-cred behind it, hit Littlefield. An eco-friendly, 300+ capacity space made punkish-chic with monthly rotating local art exhibits, Littlefield's the dream of a former environmental engineer out to prove that rock and roll is not, in fact, noise pollution. Boom. Set off by a movable partition, the performance area's walls are swathed in recycled, echo-stifling rubber, while the sun-drenched front lounge sports intricate eight-foot-tall pencil drawings of human faces, communal tables made from recycled bowling lanes, and a bar made of salvaged wood from Queens's former Benevolent and Protective Order of Elks -- let's hope they're better at protecting elks than they were their clubhouse. Drinks are a cut above most concert swill, with vino, sake, and twelve mostly-micro bottles and draughts (Coopers Green, Hitachino Red, Mai-Ur-Bock), plus cocktails from an ex- WD-50 head mixologist, including the tequila/Campari/grapefruit Bien Fria, and the rye/Cherry Heering/cynar Slippery Slope -- you'll know you've slid to the bottom when you're craving artichoke liqueur fortnightly. All opening weekend, LF's hosting free shows from Bklyn-based bands (Fri = Sisters & Golden Triangle; Sat = Cruel Black Dove & The Hundred in the Hands); both days also feature extended happy hours with $3-$6 brews -- the only Aid you need, even if it's not exactly helping you remain Live.
