This weekend, we heard Tommy Trash's huge remix of "Endorphins" by Sub Focus, and today Sub Focus has posted an updated, alternate version of this one. We'd just known this as the "DnB Edit" of "Endorphins," but now that we know it was Sub Focus linking up with Hospital boys Fred V and Grafix? Wow. It's just as amazing as when we first heard it, with the drumstep flavor at the second drop; it's just a huge remix of an already-huge tune. Should smash when this one drops on May 21.
