Kenneth Glöckler began rapping aged 13 and won the Royal Rumble battle in Stuttgart just a few years later. After street-rap OG Bushido signed him to the ersguterjunge label in 2006, Kay One hustled his way onto the charts via a succession of ciphers and feature spots. If he’s not name-dropping luxe brands and Instagram influencers, he’s underlining a party groove with a rock-solid flow. Whether he’s serving Latin-inspired rhythms on “Señorita” or narrating his rags-to-riches ascent on “Immer Mehr”, Kay One spits his verses with style.
