"Who Sent You?" by Irreversible Entanglements is an entire holistic jam of "infinite possibilities coming back around," a sprawling meditation for afro-cosmonauts, a reminder of the forms and traumas of the past, and the shape and vision of Afrotopian sounds to come. Stay on it! This is the future! This is the spectral dreaming, the reshaped soundwaves of post-Katrina, post-Osage Avenue, post-Obamacare that we borrow from to do this work, so stay on it. Who Sent You? they said from their liquid cryo-chamber, from a low-light induction field cobbled together with lithium rods, with melted down Romare Bearden and Howardena Pindell paintings, stitched with chaos fibers and placed in the center of the carrion husk of a burnt out shanty town. They took time to scrape ashen samples of what was, their souls the residue thick and caked on, that still climbs those new high-rise condominiums like moss - the only evidence that they were once there, that they were baked into the fabric of this planet - they were there fixing elevators and tossing wrenches into quantum fields until they were stopped! frisked! and turned into weird, 100-foot martyr murals on the backside, the north side, of supermarket walls-Who Sent You? is how the matrix modulation works. Dig it: Who Sent You? is the punk-rocking of jazz and the mystification of the avant-garde, a sci-fi sound from that out-soul-fire jazz quintet Irreversible Entanglements.
