Finnish Commodore 64 musician, also known with alias "Yip" (under which his music is also in HVSC).
He has made many musics that appeared in Finnish commercial C64 games, and also some musics of his have appeared in games published outside Finland. I think Netherworld has one of the nicest songs he made.
He also wrote reviews about games to MikroBITTI and C=Lehti, two major magazines about computer games.
("...I'm not going to say anything about the high score music of this game, because that was made by me." - from the review of BMX Kidz)
