Awesome about QOTSA. $20 ain't nuthin', although I suppose it comes with the irritation of having to get into the venue.
Also, and I realize this is a Tucson show, but Cat Power is playing the Rialto at the end of September (the day before Summers End Festival) so I have to make it down to see her. Missed out on the chance in 2006 when my friend reasoned that I could just see her at Coachella, but then she was in the Mojave at night with Carl Cox's bass booming over from the Sahara, making it impossible to enjoy her. She cancelled the subsequent 2 opportunities I had -- Phoenix 2008, Coachella 2013 -- but she seems to have her shit together now and isn't cancelling shows at Morrissey-levels anymore as far as I can tell.
