Vinyl Life Music has stumbled upon this interesting academic thesis discussing the roots and development of Chicago house and techno. The author, Hans T. Zeiner-Henriksen, is a PhD-student at the Department of Musicology at University of Oslo, Norway.
The essay discusses how do changes in music production processes appear in the music of the club-culture of Chicago at the beginning of the 1980s and the transition from studio-recorded acoustic material to the use of drum machines, synthesizers and sequencers, mainly Roland TB-303 (pictured on top), TR-808 and TR-909.
