Boise has a small music scene that became divided between people who like going shows and... well... The Knitting Factory, who does not give two shades of shit about their local music scene, so nobody wants to go to a show there.
Not to mention its a "gas stop" for bands, so 9 out of 10 times, a tour is going to come through there regardless of what other concerts are in the area at the time. AND Idaho has a low minimum wage... 4 potatoes an hour. its a recipe for low turnouts for sure.
