Certainly, a theoretical description is hardly seen in Boulez's writing since a certain time. This is personally one of the big dissatisfaction though three works that use the live electronics cannot buy even the score. Peel..after this..say.. almost all..for instance..include.
However, if the memory is correct (Though it is not because of looking at me and having heard it), Boulez thinks that it had gone occasionally in the lecture concerning making by oneself since the '70 age. When will obtaining time become unnecessary (Except whether to have a mind to do) though he makes it a character?
On the other hand..nowadays..Japan..Boulez..relate..remark..quality..low..one..hold.. problem..fact..deliberate..examination..lack..score..analysis..know..level..Japanese.. reference..Boulez..writing..material..hit..thing..originate..think..writer.. responsibility..think.
I feel either by finding an appropriate explanation for general even of the side that can talk when correlating with other arts about the music of the 20th century including Boulez or should talk the situation nowadays that should be supplemented for myself because it is rare (He is type that avoids an immediate reference, and because understanding is not easy alone though there is a Mr. word that Boulez dusts of course) is indescribably inconvenient.
For the time being though it is not thought that it becomes an answer so much.
