Remixing your own track isn't something that's the norm for DJs to do, but when they do I almost always love it. The remix is usually done years after the original, and that extra perspective and time guarantees that the newer version is going to be even better – more practice, more skill, better sound. The remix of Sundown by Chris Lake is fantastic for all of these reasons. The new version of Sundown is much more chill, grownup even, with the same elements that made the original beautiful.
