Having helped shape the rise of EDM to mainstream in the last five years, Swedish House Mafia's international One Last Tour has been bittersweet for fans packing their shows over the last two months. Known for the mind-blowing production of their sets, it was a given that these final shows would deliver unforgettable nights of lights, music and more for fans to revel in the dance beat wonderland. And having to be conscious of the fact that it would be their last chance for a live experience with the group, concert-goers were all the more appreciative of making their final memories with SHM. After 35,000 tickets to their Saturday night Masquerade Motel music festival, the L.A. stop on their One Last Tour, sold out in lightning speed, a second date of another 35,000-person audience was added for Friday with a lineup of some different artists to kick off the festivities before Axwell, Steve Angello, and Sebastian Ingrosso took the LED behemoth of a stage at L.A. State Historic Park. With Alesso, Sub Focus and Clockwork/Monsta playing both days, Friday night's Masquerade Motel bill featured Otto Knows, Third Party, Mat Zo and Nero, and Saturday's had the additions of Zedd, An21 & Max Vangeli, No_ID and Style of Eye.
