More than half the tickets for this year's Open Air St. Gallen 2011 have been sold, organisers say.
With less than a month to go until the event, which takes place at Sittertobel, Switzerland from 30 June to 3 July, it could sell out ahead of time.
Linkin Park, Queens of The Stone Age, The National, Dizzee Rascal, Hurts, Elbow and Boys Noize are among the acts set to play this year.
Tickets are on sale now, with a four-day ticket priced at 193CHF.
There are no day tickets for Friday or Saturday available.
