Like the bands in the Elephant Six collective (the Apples in Stereo, Neutral Milk Hotel, Olivia Tremor Control, etc.) Jack Drag believes lo-fidelity is just a state of mind. But where most lo-fi bands are content to pick at their navels in search of a song, Jack Drag leaves the cavity searches to the police. The Boston-based trio concentrates on blasting out a modern version of ’60s pop that, while recalling the Elephant Six aesthetic, sounds nothing like the bands associated with that aggregate. In fact, though, such an alliance might have helped place Jack Drag’s second album, Unisex Headwave, on the lips of many an indie hipster last year. The CD is a 10-song collection of timeless, psychedelic pop-style tunes that bristle with the sounds of effected guitars, distorted keyboards, and the passionate vocals of leader Jack Dragonetti. Get your hair done right for once when Jack Drag opens for Jen Trynin at 9:30 p.m. at Iota, 2832 Wilson Blvd., Arlington. $6. (703) 522-8340. (Christopher Porter)
