"Ebo Lala" by Mulatu Astatke
I was recently turned on to this guy, and boy was I missing out. Astatke's brand of jazz is wildly eclectic, moving between traditional jazz, Ethiopian music, funk and more--often doing so mid-song. "Ebo Lala" consists of a start and stop funk groove with heavy, Ethiopian percussion and semi-infrequent, but great, horns. The centerpiece though is the group vocals, which chant the title over and over again with little variation. Great tune by a guy worth investigating more.
