For musical tours it's usually something more like: Seattle, LA, a big city in Texas, Minneapolis OR Chicago, Atlanta, NYC and sometimes Boston. But I take your point lol

The odd thing to me is the Minneapolis or Chicago. In pure numbers, it should be Chicago every time, but Minneapolis seems to draw a strangely outsized amount of musical acts. I think it's because MSP is a big airline hub. Or something? I honestly don't know.
