Rage Against the Machine and Wilco have been rumored to be the latest line-up of the music festival in Chicago.
Some of Wilco's dates within 'Sky Blue Sky' tour in North America are rescheduled after guitarist Nels Cline was caught chicken pox.
Wilco released a written statement on their website saying that the songs used in VW running ads are licensed.
In support of latest album, Wilco will visit three different continents up to July.
For seemingly a routine for the band, Wilco's seventh album, "Sky Blue Sky" (2007) leaks on the Internet three months before its release date.
The likes of the Police, The White Stripes, Tool, and Wilco will all headline the four-day Bonnaroo Music Festival in June later this year.
