Sefiros is the performing pseudonym of Bryan Henderson, a musician from Scotland who mainly creates electronic music in such genres as ambient, electronica, industrial, and chillout.
In 2003 after becoming increasingly interested in music he began to teach himself to write and compose music, and eventually in 2004 he began to write remixes or rearrangements (ReMixes) of video game music which would be released on VGMix and later on OCRemix.
After writing and releasing these remixes for a few months he soon began to compose original music in a variety of different styles.
In the months leading up to the end of 2004, the netlabel Hellven started a contest known as Auld Lang Sine where the aim was to write and produce an album by the end of the year. The album Not There was completed for this competition and released on the 1st January 2005.
During 2005 Sefiros released another three albums: Connected, Deconstruct, and Fadeout. Both Deconstruct and Fadeout were written for other iterations of the Auld Lang Sine contest. In 2006 an EP entitled Shadow (Of A Doubt) was released. 2007 saw the release of Sefiros' fifth and sixth full length albums, Minor Disruption and Under The Roots.
In 2008 You're Not Here was released, and near the start of 2010 the album Stop Becoming was released commercially to several online stores and via the official Sefiros website.
