No reason was given for the decision, but already speculation has surfaced that long-simmering tensions between the bandmates have reached a boiling point.

According to their website, Van Halen will finish out the remainder of the shows they have scheduled for next month, including a June 26 gig at New Orleans Arena in New Orleans. But all concerts set for July through September, which included more than a few soldout stops in such cities as Baltimore, Cleveland, Detroit, Milwaukee, Philadelphia and Salt Lake City, have been put off until further notice.

Live Nation, which is promoting the trek, has yet to release information as far as makeup dates or where to obtain refunds, and a rep for the band declined to comment.
