Original track by Dirty South & Thomas Gold, featuring Kate Elsworth, Eyes Wide Open was released as a typical house hit. Felguk took it to the next level, adding a womp that leaves the listener uncontainable. The first minute of this remix gives you a look at the original, but the drop takes it from "eyes wide open" to "eyes buggin" at 1:50.
Fegulk are two Brazillian Dj's, so they must have sexy beats. Here's another one of their songs, 2Nite, which is more of the "made for radio" dubstep style.
