4. Red Hot Chili Peppers and Bruno Mars (2014)
Bruno Mars started out by amazingly whaling on the drums, at that point broke into his hit song “Locked Out of Heaven,” and all the rest was history. Mars tossed the group a curveball when he groomed out with the Red Hot Chili Peppers for a coordinated effort including their melody “Give It Away.” Even non-fans had no choice but to love it. The blend of his Temptations-inspired clothing and polarizing voice made for a performance to be remembered.
