Suicidal Tendencies and Airbourne are believed to be the first bands confirmed for Pukkelpop 2011.
The bands are listed as playing the festival in the January 11 issue of Rock Tribune magazine, which is available early to subscribers.
There is no official confirmation as yet, but the magazine is considered a very reliable source.
More names should be announced shortly.
Pukkelpop 2011 will take place in Kempische Steenweg, Belgium on 18-20 August 2011.
Pukkelpop 2011 tickets are currently not on sale. Virtual Festivals expect them to go on sale in April but keep checking back for more information on ticket availability.
