Under his moniker Mike Deal he got his first gigs in some small venues around his hometown in 2002. 2005 was the year, he was releasing his first Hard Techno productions on Labels like F.A.T.tm and Composure alongside Artists like Viper XXL and Arkus P. His Producingsound got harder and faster from year to year, so Mike decided to leave the „Schranz“ scene and get more involved with the
„FreeTek“ scene. Under his moniker Mikrotek he produced from 2006 to 2011 hard, trippy Beats above 180 bpm which was a real pleasure for him at this time . After few years „Freetekno“, the scene was dead and he decided to take a little break to regain some strength for some new projects. With new ambitions and a new image, he was starting again in 2012 under his novel moniker: Dealirium. From 2012 till now he got many releases on Labels all over the World and with MODU Records he got a nice label deal in Manchester. His style ranges from Tech House and Minimal Techno to Techno and he is refining his tracks with dark sound elements or house like grooves , which he combines with hard and driving kick drums to produce a forward-moving composition. In 2013 he and some of his friends founded the „PLEXIC Music Club“ , a association for electronic music lovers, dj´s, and producers in Upper Austria. With the opportunity to have a union , David Sama, Mike Van Oy, Rai Tinga and Dealirium decided to do their own Record Label „PLEXIC RECORDS“ in 2015 .
