As I've noticed there's one genre of music that doesn't get a look in on here thought I'd recommend my favorite Classical works.
Stravinsky- THE RITE OF SPRING, THE FIREBIRD or PETRUSHKA
Mahler- SYMPHONIES 1 or 8
Carl Orff- CARMINA BURANA(instantly recognizable)
Allegri- MISERERE MEI
Wagner- PARSIFAL(prelude) how an evil anti-semite like him could write something like that is beyond me.
or virtually any GREGORIAN CHANTING.
