L.A. rapper Kid Ink recruits the West Coast’s most reliable hitmaker, DJ Mustard, to executive produce his fourth album, and it’s a match made in heaven. Summer in the Winter is loaded with upbeat, carefree club rap that floats like a SoCal breeze. “Promise” borrows tropical house bounce for a true-love anthem infused with soaring melodies from Fetty Wap. “Rewind” is an icy-hot sex jam with a syrupy Akon hook and a sly Salt-N-Pepa nod, while the crisp, snappy title track channels poolside parties all year round.
