Northside Festival. Twin Shadow (a.k.a. George Lewis) is a standout among the many one-man laptop-wave acts moping around North Brooklyn these days. The soothing, dancey tracks on his upcoming release, Forget, will live on Terrible Records, the label helmed by Grizzly Bear's Chris Taylor. Psych-pop is on the bill earlier, or at least the irreverent approach thereto by Philly's Drink Up Buttercup. There's also Oberhofer, whose namesake, the superyoung Brad Oberhofer, creates one-man bedroom indie-pop you'd think was the result of more sophisticated techniques.
