Trettmann, aka "Tretti", is the rapper with the unmistakable flow from Karl-Marx-Stadt (Chemnitz). His album #DIY from 2017 brought him his big breakthrough after the initial scene hype and is now considered a modern classic that transcends genre boundaries with dancehall, trap and grime. The album "Trettmann", released in 2019, reached number 2 in the German charts. After a three-year hiatus combined with the coronavirus break, Trettmann returned in 2023 with the album "Insomnia", which simultaneously concluded his era with KitschKrieg and dealt with the separation from his long-term partner. With hits such as "Zeit steht", "Knöcheltief" and "Stolpersteine" and his unique flow, Trettmann remains one of the most sought-after artists in Germany. "Tretti" is firmly anchored in the German music scene, shaping it with his versatile style ranging from classic rap to dancehall vibes.
