Heinrich Weingartner has performed under many DJ names, playing a wide range of genres across diverse nightclub scenes through the years. 15 years ago, when he started playing music, he focused on flashy and drop-centred techno music produced by current trends and producers. After a five-year hiatus from DJing, he picked it up again in 2024 - mainly thanks to the Pizza Italo Disco DJ team, hosting a monthly evening of Italo Disco at the Kaffee Kind in Lucerne, Switzerland.
Today, under the moniker Kolleg Acid, Heinrich is intensely chasing for disco tunes on vinyl, discovering the influences and roots of the electronic music that he started out with. Additionally, he has grown an appreciation for flamboyant vocals and eccentric sound choices. His sets and mixes are rich in variety, moody, playful and mostly crafted for the dancefloor.
