The rolling thunder of “Challa” kicks off Shashwat Sachdev’s hard-hitting soundtrack to Aditya Dhar’s military blockbuster, its clashing of vocal harmonies and scorching dubstep echoing the feel of India’s retaliation to a devastating militant attack. The simmering “Jagga Jiteya” brings big bass drops as Dee MC spits fire over Daler Mehndi’s searing vocals. These contrast with acoustic moments both bittersweet (“Behe Chala”) and brimming with defiance (“Manzar Hai Yeh Naya”). Ultimately, both sides unite on the closing “Jigra”, with space to breathe between moments of gunshot percussion.
