Philosopher Roger Scruton and his Music of the Future

I recall reading this past Sunday, in his
The Aesthetics of Music (1997),
that British philosopher (and composer and ecologist)
Roger Scruton most admires the contemporary
classical musical works of John Adams, Robin Holloway,
Nicholas Maw, and (the late) Alfred Schnittke.
It is an interesting and provocative, select list.
(I will ignore, here, his comment on one of
Sir Harrison Birtwistle's operas.)
