Shlohmo has probably the most telling name of any electronic artist out there. Half the elements he uses sound like they're being played in half time through an underwater filter, and "Later" is no exception. There's a vocal sample in there somewhere in the the six minutes of frenetic, steadily intensifying loops. This beast will find a home on the LA beatmaker's March 5 release, entitled Laid Out.
If you find yourself in a Shlohmo mood after listening to this, make sure to check out the half hour mix he did for BBC 1.
