I heard Okmalumkoolkat for the first time with the remix of Fancy Footwork. Curious to what it was based on, I started looking for the original, and found the Holy Oxygen EP.
It was of much higher quality than I expected, and very different from all other hiphop-influenced music I have heard.
Holy Oxygen II is as different, but much more matured. Watch these guys!
Favorite track: Zweitbester (Second Best).
