Jonne Valtonen, a.k.a. Purple Motion, was the lead composer for Future Crew, one of the most widely popular demo group of the 1990s. He won multiple awards, most notably at the Finnish demo-party Assembly, for his work throughout the demoscene. After Future Crew disbanded in the mid-90s, Valtonen continued to compose songs, doing some commission work for computer and video games and wrote the scores for several stage plays under the production company Valtone. In 2004 he released his first professionally mastered audio CD, titled Musicdisk. <a href="https://www.last.fm/music/Purple+Motion">Read more on Last.fm</a>.
