Rau first surfaced with the 2008 EP Gribuntal, issued by Gedankensport. He made his first appearance on Smallville Records in 2009, sharing a split single with Sven Tasnadi. The label then released his debut full-length Asper Clouds, as well as a collaboration with Smallpeople, in 2010. Singles on other labels such as Giegling, Hypercolour, and Pampa preceded Rau's second Smallville full-length, Two, in 2012. He also released collaborations with producers like Jacques Bon (as Bon Rau) and Sebastian Genz (as Roaming) and released a few singles under the pseudonym Rhythmus Günther starting in 2013. Rau continued releasing EPs including Mehris Mood (2014) and Yamato (2016) before issuing his third full-length, F.M.E Hustle, on Money $ex Records in 2018. A harder, faster single titled "Beasts" was issued by the Richard Fearless-run Drone imprint in 2019. ~ Paul Simpson, Rovi
