This is the Japanese edition of the fourth disc of Warner Classics' fresh and exciting Ligeti Project--the US version is considerably easier to obtain. The Ligeti Project is a continuation of Sony's "Gyorgy Ligeti Edition" attempt to put the great composer's entire body of work on disc. This installment contains the composer's recent "Hamburg Concerto" as well as two other works performed by the Asko/Schoenberg Ensemble. If you're new to Ligeti, this is worth getting because it contains his "Requiem", one of his most famous and also most accessible works, in a new performance by the Berliner Philharmonik.
