Say you're a 1970s musician, who's been paying your dues. Finally your break comes. You get a hit, you get some fame and money, and the record company arranges for you to tour. And then you go on the road, and watch your polyester-clad a$$ get smoked every night by The Most Dangerous Opening Act In Rock.

Best concert I ever saw had MF opening, not even billed, but they damned near stole the show. The better known acts on the bill jacked it up as hard as they could, because of them.
