The American installation of Virgin Mobile Fest will return to Pimlico Race Course Aug. 9-10, and the lineup has five big reasons to mark your calendars and purchase tickets ASAP: Kanye West, Foo Fighters, Nine Inch Nails, Jack Johnson, and reunited alt-rockers Stone Temple Pilots are on the bill for the fest's third annual installation.

Foo Fighters, the busy boys they are, will also headline Canada's V-Fest, scheduled to hit Toronto's Island Park Sept. 6-7, alongside Oasis, Bloc Party, and Paul Weller.

A complete bill for Baltimore's V-Fest has yet to be announced, but more acts will be revealed in the coming weeks.
