The horns are the primary element that will creep into your mind. Subconsciously circling about the listener like a spider, trapping the ear with its subtle sweetness. However, brass is only part of the equation. As the bass continuously thumps along bringing with it a tempo that forces you onto the dance floor. The drums push the limits rolling and smashing along with a pedal to the floor passion. The guitar plays off the onslaught of percussion, shredding with a cruise control consistency. Energy will be at a premium when Hassidic punk rockers Electric Simcha take to the stage at The Blockley. They’ll be sharing the bill with West Philadelphia Orchestra, whose hypnotic interplay of strings and horns is a modern sound yet does not drift too far from traditional roots. The Blockley, 3801 Chestnut St., 9pm, $10, 21+ – Michael Colavita
