There are more than one artist named NSL.

1) NSL emerged in 2005 from the ashes of the danish psytrance dj & act Mindfly (supported by Chris Organic and the godfather of german psytrance DJ Antaro), who had a handful of releases from 2001-2005.

Behind the project is Lars Knudsen (born 28th october 1975 - currently living in Copenhagen, Denmark), who's no stranger to the music biz, having been released on various labels (Sub Machine, Organic Records, di:lemma/Warner, Jetlag Digtial and more).
Lars has been involved in music since 1992, starting out with trackers and have delivered music for demoscene-groups such as Triloxy, Renegades and defacto2 as Dr. Retro.
In the mid 90’s he was one half of the danish synth-act d:code, but soon went on to explore other genres within electronic music (d'n'b, electronica, trance, house and psytrance.).

Now the style has moved from synth-pop and psytrance to pure emotional progressive music.
Both as a dj and artist it's all about progressive house/-trance, tech, deep, electro and funky music.
All boiled down to NSL - No Sonic Limits.

NOTE: This artist changed name to No Sonic Limits.
