In November 2001, Sub Rosa published Henri Pousseur's 8 Parabolic Studies in a box of 4 CDs - these electronic pieces have been created in 1972 at the WDR studios in Cologne. The idea was to ask other musicians, of different generations, to attempt a new mix on the basis of these eight studies. The first mix (and not re-mix) was a re-interpretation by Henri Pousseur himself - this laid the foundation stone of the edifice. Contrary to the mixes carried out thirty years ago, these were made digitally. The second mix was Robert Hampson's (aka Main) - quite nervous of the master's reaction, who was present during the set. Robert, who holds an exhaustive knowledge of electronic music from it's origins and of all it's aspects - even of the more obscure ones - gave a personal but faithful interpretation of Pousseur's studies. Another degree of alteration was highlighted by Philip Jeck, who created a massive and powerful set, adding sounds from other sources (which is totally allowed according to Pousseur's original concept). And finally, Oval - according to the process that is quintessential to his work, Markus Popp could only produce a piece far removed from it's sources; since it is within sound itself that all sonorous source passes through the Oval-process, thus becoming Oval-music - that is, music having it's very own properties.
