If you miss the high-speed, high-skills, hip-hop instrumental heroics that seemed to slip through RJD2’s cracks somewhere between Deadringer and Since We Last Spoke, you may want to give “The Countdown Part 2,” the second track from the X-Ecutioners’ Revolutions, more than one spin. In under two minutes, the built-to-scratch trio of Roc Raida, Rob Swift and Total Eclipse take their craft into uncharted territories, instrumentally shaping new-school soul on scrambled verbal clips, big wax cuts and a sitar-built bridge that is one of this year’s best moments in hip-hop. Expect high energy, big fun and the upper echelon of turntable alacrity and adroitness. Northern State, Wylde Bunch and Kerbloki open. The show starts at 9:30 p.m. and tickets are $13 in advance.
