Attitude has announced that due to circumstances beyond their control, they have to call off their current U.S. tour:

we've been contacting individual promoters one at a time in hopes of somehow starting the tour late. at this point in time it's very clear that that won't be possible. so if we haven't gotten in touch with you yet we will very soon.

we're very sorry about this and we'll be doing whatever it takes to make up every single date.
