Anytime I see something with Ellie Goulding I have no choice but to stop what I'm doing an listen. One of my favorite songs of hers "Tessellate" (which is her cover of Alt-J's single, also an excellent track) received a remix from Kastle, who is proving to be one of the better producers out. He keeps Goulding's sultry and unique vocals intact and places it over a mellow trap beat that captivates from the very start. What could be even better about this remix? Oh, Kastle is giving it away for free. Fuck yeah.
