Kalle Krass was active as Cap10Nemo from 2005 to 2015 with his band 56BOYS and is a founding member of the underground cult radio project Radio Dorfdepp. His first solo release (NEMO) dropped in 2011. He studied acting at the University of Music and Theatre in Hamburg and appeared as both actor and musician on stages across the German-speaking world – including Thalia Theater Hamburg, Deutsches Theater Berlin, and Theater Basel.
At the Nationaltheater Mannheim, he met Kriton Ioanides-Klinger (Chrome Animals). The two collaborated on several EPs, including Schwarzer Papagei, Kalle vs Nemo, and Sternzeichen Stur. Alongside Fritz Bayer, Philipp Schwendke, and Phil Paruschke, he co-founded Krazy Kapelle, who opened for Le Fly on tour and released the EP Floaten.
Together with his sister Nona Alada, he founded the label GHR Music, through which—supported by Initiative Musik—they released various singles and music videos. Kalle has also worked with Alexa Voss and Heen Martens (Synapsen im Grinder), and recorded multiple tracks with DJ Robert Smith.
His mixtapes The Allerlast I & II were created during late-night home studio sessions with AkiraBeatz, Nona Alada, and dia.X, paying tribute to the sound and spirit of the ’90s. Most recently, he released Spiegelbild in collaboration with Yvon from Songs for Joy, earning spots on over 100 playlists.
