I saw that Strokes/Peppers combo a few weeks ago here in Det. I was good. I'm not really a fan of either band, but I had fun. The only stadium-sized acts I've seen in the last 20 years are Phish and whatever the current incarnation of the Dead are calling themselves at the time, so it was a different experience and way different crowd. But worth the price of admission, as far as concerts these days go (like $130 for ok-to-not-that-great seats).
Now I'm struggling with whether to buy tickets for The Boss in March. Anything not behind the stage are going for a minimum of $225 or some crazy shit (like nosebleeds), so at that point if I'm going to commit, I guess I might as well buy the $300 decent seats. What's the difference? Anyway, go. You'll have a great time, and so will your son. Chad Smith is an insanely good drummer, so your kid will learn something.
