This project from two Chicago artists, singer Jeremih accompanied by the omnipresent Chance the Rapper, came flying over the transom like a Secret Santa surprise. It's nine tracks that, rather than a typical trite holiday toss-off, is legit and Chicago — more specifically, South Side — through and through. It pulses with ambition and that peculiar restlessness that permeates music these days, like the artists had more ideas than time and tried to stuff everything in. "Merry Christmas" won't find its way into the holiday music pantheon alongside a classic such as "Christmas in Hollis," but it's almost always a hoot.
