Voltage marks his return to Kool with 4am (Don’t Wait Up For Me), as the veteran producer brings in vocalist Slay into the fold. Between them, the artists create a highly infectious anthem, with a strong identity of rave-renaissance, intertwined with both rap and soulful vocals over the top of Voltage’s 2-step instrumental. The result is an anthemic track that showcases Voltage’s chameleon-like versatility and introduces a debut collaboration with one of the scene’s most exciting vocal prospects.
