A major Spokane Arena concert will be announced first thing Friday morning.

Nope, I don't know what it is. Everyone is keeping mum.

The only hint: It will apparently be a Live Nation show, which implies it will be a concert and not a monster truck rally or dinosaur extravaganza.

The only other hint? I am told it'll be worth the wait.

Does anybody out there have any guesses? Or even better, any actual information?
