Markus Castrén

Markus Castrén is a composer who was employed as a trainee at Nokia during 2002. He is known to have written some ringtones, although it is not known which ones. He is believed to have composed the Jungle ringtone, and possibly other Nokia N-Gage ringtones, which feature a more dance-inspired sound compared to most other Nokia ringtones at the time. After leaving, three composers immediately joined in his place: Aleksi Eeben, Hannu af Ursin and Henry Daw.
