Van Halen have postponed over 30 dates on their 2012 North American tour, beginning with their show scheduled for July 7 at Uncasville, Ct. and ending with their planned Sept. 25 performance in Milwaukee.

No reason or official statement has been given for these postponements, nor is there any word on when the rescheduled dates might be announced. The timing seems odd, as the band announced earlier this week they were extending the tour with eight new shows.

A press release from the EnergySolutions Arena in Salt Lake City, Utah, where the band was scheduled to perform in September simply reads: "The Van Halen show at EnergySolutions Arena Tuesday, September 4th has been temporarily postponed. Future dates to be announced."

The band will apparently still be performing throughout May and June, with their next show scheduled for Saturday, May 19 in St. Paul, Minn, followed by 13 more dates culminating on June 26 in New Orleans. A complete schedule of both postponed and still-scheduled Van Halen concerts follows below.
