This weekend in Alabama, Hangout Music Festival is kicking off it's 5th event as one of the coolest spring time festivals in North America. Just yesterday, the festival announced a change in their line up – and a big one. Due to a surgery on his vocal chords during the same time, Sam Smith had to back out of his head lining performance this weekend, and now because of that EDM Supergroup Jack Ü [Diplo x Skrillex] will take his spot, ending out Friday night of the festival. Some fans may be disappointment in the recent announcement, others may be stoked, either way the talent trade was fair on this one IMO – Smith for Jack Ü sounds like a fair switch to me, especially so last minute.
