I am sorry for late the answer.

Boulez..Japan..Boulez..music..speech..situation..have..dissatisfied..chiefly..at

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?
