Written by Wu-Tang's Gza/Genius, performed by Jim Jarmusch. (Not sure who produced it, though I believe it's Preservation).
Here's a recent New York Times piece on The Gza/Genius and his new enterprise to teach science in public school through the use of hip hop rhymes. Wu-Tang is for the babies, in case you didn't know.
From the article:
Growing up in the Park Hill Houses on Staten Island, he was curious about the physical world but bored with school. Hip-hop became his outlet for showing off intellectually.
“It was always about crafting the best rhyme in the most articulate, witty or smart way,” he said. "For us, it was always about educating the listener."
It took him more than two decades to develop his curiosity about science into “Dark Matter,” an album now in the writing stage, which he hopes will bring his fans to astrophysics, starting with the Big Bang.
