I'll say this. When it comes to live performance, I'm only into theatrical productions, classical, and opera. 

You folks who are primarily into pop, rock  or other such forms of live performance put up with way too much BS. Will call is completely standard at every theatre, symphony, philharmonic orchestra, and opera house I have been to. Some of them will mail you the tickets as well. Visiting hours or days before a production and buying a paper ticket in person is an option also.
