Jussi-Matti Salmela (born August 11, 1979), better known by his stage name Elwood, is a demoscene musician from Kankaanpää, Finland. His alternative alias is known as Elwood79 which he used throughout his releases at the previous site of MP3.com. He has produced the soundtrack to a short-movie called Teräskolikkoarkku.

Elwood is additionally known as Magellanic Milk, after September 2010.

Elwood released 15 module compositions throughout the 1990s written in FastTracker 2, a few of which have been featured in home-made levels for video games like Jazz Jackrabbit 2 , Unreal Tournament , Mario Forever and Cyberruner. They can be fetched at different sites, but primarily at the Mod Archive. Most of them have received top rates by reviewers there, calculating an artist average of at least 9 out of 10 points.

By the end of the 1990s he stopped releasing for the tracking scene and moved to MIDI software, producing a number of tracks similar to his old style, though having a more "mainstream" flavour to them. Many of the MP3 tracks from the newer timeline were released at the previous site of MP3.com. Last tracks from that era that he has been known to released are Low Horizon and Waverider Remix 2003 from the mentioned year. Past & Present was composed for Razor 1911, a warez and demogroup from Norway.

During late 2003 and early 2004 he organised the band LooM, which in spite of all the announcements hasn't yet released any completed material.

Demo clips show that LooM music is quite different from the style of Elwood's solo works, this time as a fusion with rock elements.

According to the previous contact info on the LooM project, Elwood now lives in the bigger Finnish city of Pori, attending a school to prepare a possible education in media, while his cooperative partner Juuso Kemi (student buddy from his old high school) lives in Tampere. Juuso Kemi is featured as one of the producers behind the short-movie Teräskolikkoarkku, where he additionally made an actor appearance. Their album Electricities is apparently still under its way, after the site was updated again in 2006, standing still for almost two years.

On September 16, 2010, he released his first commercial music entry under the alias Magellanic Milk.

The track represents a continuation on the melodic expedition started by Elwood, building from the demoscene and contemporary sounds and styles.

Elwood's music has received high reviews throughout the demoscene websites, like ModArchive, MODPlug Central, United Trackers and several additional ones which had been active in the 90's but are now offline, like Trax In Space and homemusic.cc. His music is regularly remixed and brought up in the demoscene.

Elwood isn't a public person and there's quite little information on his personal life, the only sources being the bio section on his old homepage Elwood's World Of Music, which is now offline, and scarce comments in module files themselves.
