I've been hearing a lot about the iHeartRadio music festival, which was held in Las Vegas last weekend. I'm sure it's the same for everyone else who tunes into Milwaukee radio. Local stations in the IHeartRadio network include Oldies 95.7, FM 106.1 and 97.3 Radio Now.

It seemed like a great idea to me, and frankly I was amazed that anyone could pull off such a monumental project. Getting all those stars together at one time to sing their radio hits - how does that work? How many managers do you have to deal with, how many contracts need to be made out, and with what provisions? Doesn't Britney Spears only want green M&M's in her dressing room, or something? (Maybe I'm just making that up.)

And most of all, I wondered how these megastars share a stage. That's a lot of talent, a lot of ego.

As it turns out, some of them couldn't. 

Billy Joe Armstrong had a massive meltdown when told he only had one minute left on stage. You can watch the video on Jesse Mitchell's blog (if you don't mind hearing the F-word...a lot) so I won't go into the details, but it suffices to say that he smashed his guitar. Smashed his guitar. Like he's Pete Townshend.

Except he's not.

Well, we certainly know he's not Justin Bieber either, because he yelled that as he was smashing the guitar. 

Green Day apologized today and Armstrong entered rehab, that tried-and-true face-saving move.

I've attended and reviewed plenty of concerts and interviewed plenty of musicians. 99% of them have been friendly, polite and self-deprecating. But then there's that 1%.

I don't know what to make of this. Is it just another rock n' roll moment, par for the course at a concert like this? The tantrum of a spoiled artist? Is a talented musician entitled or even expected to act like this? And if he didn't, what would we all talk about?
