TCTS has done a couple of superb remixes in the past, most notably his remix of "Here" by Syron (check it out in the mixtape). He's just released a great new remix of "On & On" by Snakehips. Check it out.
Justin Vernon is one busy guy. Check out the first track from his latest project, Volcano Choir. The track's taken from their forthcoming album, Repave, which is due out via Jagjaguwar in September.
