Bela Bartok - 27 Two and Three Part Choruses, for Children's and Female Voices (Choral/Classical)

Bela Bartok is an extremely interesting Hungarian composer who is considered to be one of the most important composers of the 20th century. He was invested in folk music, which I think is very cool and beneficial in any musician, and although I know him more for his full Orchestral works, he actually also wrote a BUNCH of two and three part choruses for children and female vocals and they're pretty cool. I expected them to be somewhat atonal or harmonically unconventional, but surprisingly they have a sort of classical feel to them. Try listening to just one: Bolyongas, and if you like it you can find a pretty good recording of the rest here on Grooveshark.
