Do you listen to xenharmonic (including microtonal) music? It's good stuff. It's music that uses different tones than the twelve commonly in use today.
I recommend this album for beginners.

Bohlen-Pierce, which doesn't show up in this album, is incredibly interesting, it doesn't even use the octave (doubling of pitch)
