Here's one to bump while the last days of summer come to an end. Tona teams up with Kayo and Chicago producer Slot-A for "Ol Time Sake," a one-off single ahead of his upcoming album Carpe Diem. Slot-A sets the scene with a futuristic pitched-up soul vibe over some banging drums. As usual, Tona does his thing: precise flow, impeccable delivery. Kayo's technical progression continues to shine through here too -- it'll be long past due when his official Black Box album eventually drops. Stream and download "Ol Time Sake" below and stay tuned for Tona's album, set to drop in mid-September.
