The impostors

There's a long-running Halloween tradition in Boston of bands dressing up as the musicians they admire. Tonight at Great Scott, for example, a number of groups will celebrate the holiday by paying tribute to acts they love. The Perennials will be the Strokes, Wonderful Spells (below) will be the Kinks, and the Sun Lee Sunbeam will be Elastica. DJs Ken and Michael V, who run the night, will, as far as we know, be playing themselves. 9 p.m. $10. Great Scott, 1222 Commonwealth Ave., Allston, 617-566-9014. www.thepillboston.com
