Started connecting my neighbours hifi installation to that of my parents and therefore blowing up amps and speakers in 1979, the ultimate year of Disco (Donna, Diana, Chic, Sylvester) [7" vinyl].
Picked up mixing again in the late 80s (SOS band, Alexander O’Neal) [12" vinyl] and earned money as a DJ in the early 90s (Frankie Knuckles, C&C Music Factory, Robin S) [CD's]. I even created some (home-)studio tracks [Atari 1040ste, Cubase, DX-7, Moog, AKAI sampler].
Then started DJ-ing occasionally at local parties again from 2012 and on (Bruno Marrs, Daft Punk, Oliver Heldens) [iPad / MacBook]
