Markus Castrén

Markus Castrén is a composer who was employed as a trainee at Nokia during 2002. Both composers are known to have worked on ringtones for the Nokia N-Gage and other phones using the Mango soundbank, such as the Nokia 3300 and 7600. After leaving, three composers immediately joined in his place: Aleksi Eeben, Hannu af Ursin and Henry Daw.

Outside of Nokia, he was a demoscene musician known as Slice, Mark 1 and later Ganja and was part of the Amiga demo group Nerve Axis. Following his employment at Nokia he continued his studies at school, then became a DVD author. He also composed music for a handful of local Finnish commercials as well as sending demos to record labels, and has not been active in the field of music since the mid-2000s.
