Swedish House Mafia fans who were looking to attend the Masquerade Motel at this year’s Ultra Music Festival (an additional 141 acts announced) better not hold their breath as the event has now sold out in under 2 hours – to make matters worse scalpers are selling tickets for up to $300 on the popular Craigslist site!

Although the full line-up has not been officially revealed Swedish House Mafia’s Axwell tweeted that soft-cheese fan Calvin Harris will be a main support act. Two other revellers from last years Masquerade Motel, A-Trak and Dirty South have already been commited to the Ultra lineup and would not feature again.

Inside sources have stated that SHM plan to release a second batch of tickets to counter the scalers closer to the date.
