@evan LOL. They don't yet have anyone that they love so intensely that they are very interested to see them in concert, but when they do, I'll go to the end of the world for that.
I did take the older one to see the LEGENDARY Russian band Aquarium in Boston. I'm much more of their fan than he is, but I did use some of their quieter songs as lullabies when he was much younger, and he identified them. They are playing in Toronto and some other North American cities soon.
