There are several artists under this name:
1) Xander Linnet, a Danish-singing R&B artist whose debut album was released in February 2011, is the son of Danish artist Anne Linnet.
2) Xander is just a guy who likes to play with Ableton Live.
He has several tracks of mediocre electronic trip-hop noise. He began for personal amusement and is not distributed.
3) Xander is a song writer currently writing songs under several different styles including blues, electro/techno and classical. Currently the work is unreleased, and until funding is found the music is enjoyed by those of the Emilie Autumn forum (or at least the people who know him there).
4) Xander Gaines. His single "The Look" was produced by Jonny McGovern and is released on "The Legends Ball: The East Village Mixtape II"
