Already at an early stage, Tomas Weiss built a deep connection to many different musical genres. From 1997 to 2006, he worked as an electronic DJ in several national/international clubs and was a regular moderator on different radio stations. During this time he also owned the music store "el culto" - a vinyl shop specialized in electronic music.

In 2005 he finished creating his own studio and gradually moved his musical career towards composing, producing and mastering. He also transformed el culto into a „musical portal“ with several linked sub-labels, with focus on Ambient, Slow Motion, Space and Sleep music.

Numerous projects and collaborations like Nautic Depths, Aestrata and Quiet Calling followed in reflection of his aim to create high quality music, exploring and breaking artistic boundaries - his releases now span many different styles including Ambient, Electronica, IDM as well as unusual genre combinations.

In 2015 he composed the complete Original Sound Track for „Cafe Journal“, an independent movie by the Romanian director Ciprian Brasoveanu.

In 2017 he started „Deep Colours“ - a 2-hours radio show by el culto, moderated by Tomas Weiss.
