Structures for two pianos is one of Boulez's most difficult and, let's say it, arid works... They don't leave much room for the performers to do anything other than realize it, put it in place... If he there is a "poetic, sensitive statement in this work" then there is in the poetry of exactitude and in the emotion which can arise from the perfection of the forms and the application of the concept of the series of twelve sounds invented by Schoenberg to the other parameters of the music (duration, pitches, intensity, attacks) which will lead to complete serialism... Between us, even an admirer of Boulez, including myself, can still be a little stuck in the face of the two books of structures. .. and prefer by far, very far, the Piano Notations, some of which have been orchestrated: it's magnificent. These are twelve pieces for piano, each of twelve measures and using the dodecaphony in an inspired way. But you definitely know all that!
Pi-hsien Chen recorded them with Boulez's three piano sonatas... on Hat Hut Records... and also many other piano works from the 20th century. Including the Klavierstücke of Stockhausen, Messiaen, Höller, etc. and also... Bach's Goldberg Variations which are also a "mathematical" work that appeals to objectivists and subjectivists!!!
