Yes, All American Rejects have canceled a number of shows this summer including the Warped tour and a Canadian leg with Simple Plan. They claim that they want to finish up their new album and that the shows will get in the way with studio time. If you ask me, live is more important. Finish your shows. The fans will always be around for another album.
The AAR site had this to say:
So planning stuff six months in advance can be tough, and can come back to bite ya in the ass sometimes, and unfortunately we’ve walked into just a situation… We’re still working really diligently on the new record, and its coming along, but we’re in a spot where we just can’t break away from it right now, which means we gotta cancel some shows. It was a really tough decision, but it came down to potentially having to push the record back til next year, and i don’t know about you guys, but we just can’t wait that long. So we’re bummed to say it, but we’re not doing Warped Tour this year or our Canadian tour with Simple Plan. We can’t apologize enough to all you guys who were excited to see us, and hopefully we can make it up to you really soon (hopefully first with a really good record). We also can’t give enough apologies to everyone involved with Warped Tour and Simple Plan. Thank you so much for understanding. We are still doing the handful of shows with Bon Jovi, so if you’re coming out to those, we’ll see ya there!
If I was a fan, I would be hoping for a damn good album in return for my chance to see them live.
