I actually like Messiaen's organ music. It is quite severe
and intellectual in its structure, but I do like
his rhythmic sense and non-traditional sound inventions.
I never feel the presence of God through his music though.
Only Machaut can do that for me. Maybe Leonin and Perotin.
Or some of the dutch masters.
JOHANN SEBASTION BACH....
It's rather difficult to define "the presence of God...[felt] through music, I think.
But Gregorian Chant (not psalm-chant--the real stuff) can give one a lift, anyhow.
