This illustration was made for the Belgian electronic music label "Narcosis". The label is focusing on "acid-techno" made with hardware machines and this is what it is about: tweaking synthesizers and other sonic devices, like the infamous TB-303 from Roland and ultimately to become part of the machine.
The piece has been fully hand drawn with black ballpoint pen on paper in 2013. Its original size is around 31x31cm (13,7 x 13,7 in).
The file is a 300dpi Jpeg - 3000 x 3219 px.
