A collection of a few historic and otherwise mostly contemporary works from the Institute of Sonology (founded 1960) in Utrecht. Xenakis's Concret PH and Varese's Poeme Electronique - both recorded at the Phillips laboratory of the natural sciences (precursor of the Institute) - appear here reconstructed for the first time from rediscovered original masters. Otherwise, the highlight must be Logos Protos, a substantial new work from old hand Konrad Boehmer, apocalyptic both in form and content. Another interesting rarity is Ligeti's 1958 score, impossible to complete at the time (because the technology wasn't up to it), in a newly realised version (1996). Otherwise the works here are all products of the Institute by young composers produced in the last 5 years. A useful compilation.
