Mark van der Schoot , known by his stage name Maduk, is a Dutch drum and bass music producer and DJ from Amsterdam. He has released music on Hospital Records, Liquicity Records, Viper Recordings as well as Monstercat and Fokuz Recordings. He released his first album Never Give Up at Hospital Records on 29 April 2016. Together with Maris Goudzwaard, he founded Liquicity.

Goudzwaard created his Liquicity YouTube channel in 2008, as part of his hobby to collect and promote a particular type of drum and bass music he liked. The channel quickly attracted fans –who would become known as “Liquicitizens”– with the same musical taste, and artists from the same genre featured on the channel gradually formed a close group.

In the summer of 2011, Goudzwaard heard Maduk’s first track, “Avalon”, and contacted him to promote it on the Liquicity channel, with success. The cooperation between the two evolved into a team, and Liquicity Records was established as a label a few months later.

In January 2013, they founded a new company for Liquicity events and label matters. Through the combination of music promotion, record label and events, the duo’s hobby grew out to a full-time job.
