Northside Festival. The Screaming Eagle of Soul has landed. Daptone-abetted song man Charles Bradley, a showstopping performer with a searing, James Brown–esque rasp, visits House of Vans for a free (with R.S.V.P.) gig. Expect nothing short of pure, uncut soul. Opening is Canadian singer Mac DeMarco, who peddles pouty, surreally stylized lo-fi pop in support of a brand-new disc, Salad Days.
