A-Trak and Oliver have long been two of dance music’s absolute coolest. On their collab “Zamboni,” these Fool’s Gold family members drop the temperature (and the bass) even further, crafting an iced-out funkstravaganza of synth squiggles and cut up ’80s drumrolls laid atop one insistent, brain-rattling acid riff. Get in the rink with these party boys and lose control. Sleeve by Kidmograph.
