Van Halen's summer tour dates have been abruptly postponed with no explanation from the band.

Effective after their June 26 show in New Orleans, Van Halen has decided to postpone more than 30 long-planned dates, including shows in Milwaukee, Detroit, Cleveland, Salt Lake City and El Paso.

Local promoters United Concerts and AEG issued statements regarding some postponed shows to local media, including the Salt Lake Tribune and Las Cruces Sun-News but no details have been offered yet about rescheduled dates or refunds, according to Rolling Stone.

Live Nation, who is promoting most of the tour, has yet to comment on the postponed Van Halen tour dates.

As the news comes to somewhat of a surprise to fans, as well as promoters, several arena reps that are featuring the band on their websites seem to be pretty angy about the recent development.

You want to know the absolute fuckin' truth? I have no fuckin' idea, a concert-business source with knowledge of the tour told Rolling Stone.

It's selling pretty good - I don't know why they would say it's being canceled, a source at the Mohegan Sun Arena in Uncasville, Connecticut, where the band was supposed to perform on July 7th, told Rolling Stone

While there are some tour dates that have not been canceled, they are mostly shows that have not yet sold out -- including this a June 19 show in Minneapolis and June 20 show in Dallas.

We're selling really well, Jack Larson, vice president and general manager of the Xcel Energy Center, told the magazine. We're looking forward to it, he added.

Van Halen announced the Summer Tour dates with David Lee Roth on board, back in January. Van Halen reunited with David Lee Roth for a 2007 tour and hit the road again with him in February. The band released its first new album with Roth, A Different Kind of Truth, earlier that month

UPDATE: A Van Halen source has told Rolling Stone that the band is arguing like mad, they are fighting.
