German rapper and party pop singer. Tream is Germany's first Schlager rapper, no question. He started mixing party hits and rap early on in his song "Verliebt verloren." His earlier releases still feature elements of cloud rap, while songs like "Lebenslang," "Hinters Bierzelt," "Goldmarie," and "3er BMW" move musically between rap, party hits, electronic dance music, and happy hardstyle.
