Well here's the deal. I work a fulltime job that pays decent for a single guy and I pay a fairly reasonable rent downtown with utilities included. I am also a wheelchair user because of a neurological condition I got when I was a teenager, which sucks yeh, but it also gives me VIP seating in most venues which makes shows very pleasant and worthwhile. I was dating a girl for half a year and my concert attendance slowed down alot but now that I am single again I only have to buy one ticket to everything, which makes it alot more reasonable.
Some shows I went to this past year: My Morning Jacket, Monsters of Folk, Mark Kozelek, Joanna Newsom, Elvis Perkins, Josh Ritter, Devendra Banhart, Mountain Goats, Kurt Vile, Pavement, John Prine, Swell Season, David Cross, Paul F Tompkins, Louis CK, Soupjam Stevens, Bill Callahan, The Flaming Lips, Explosions in the Sky, Black Lips, She & Him, Godspeed, The Felice Brothers, Old Crow Medicine Show, David Rawlings Machine, Justin Townes Earle, Neil Young
But like when I go to shows at the theatres in town the ADA section is usually 10 feet from the stage. So that makes a $50 tickets seem more worth it.
So going to shows is pretty confortable for me. But I can understand why others might plan their attendance more carefully.
