Tomorrow Comes The Harvest are Detroit techno pioneer Jeff Mills, Indian tabla player Prabhu Edouard and Guyanese keyboardist Jean-Phi Dary. Together they create a transcendental mix of live improvisation, wild rhythm, electronic and acoustic wonder. I spoke to them ahead of their Barcelona gig, on November 2 at Jazztronica, about reading a crowd, Tony Allen, spiritual process and going on forever.
