Dokaka - "Angel of Death". Dokaka was only added to the list of Björk collaborators on the 14th of this month, two days after he wrapped recording sessions with her in New York.

Dokaka is a Japanese beatbox artists whose onomatopoeic name is derived from a series of percussive syllables he uses for making drumbeats in his acapella recordings. This tune is one of the remakes for which he's gathered a small cult fanbase. "Angel of Death," a Slayer standard is prime fodder for one of Dokaka's vocal arrangements. Afterall, he doesn't just beatbox the drumbeats; he adds a little of the touch of what Björk calls "modern doo-wop," figuring in layers of instrumental melodic and harmonic textures. It's not too difficult to see how he'd be of use in the new Björk album. If you're just joining in, this post explains this week's prospectus.

I haven't found much information on him or his background. His website sort of skimps on the biographical details, but it does offer tons more tracks to download! Enjoy.
