Muralist Joe Pagac does a lot of work around Tucson. One of the places he's painted most is the east side of the Rialto Theatre. His concert murals popped up so often there that I gave up even trying to photograph them all (which is a bit sad; they're always great).
Every time I went by in the first half of 2010, he'd have single murals stretching the length of the space (just south of Congress Street as you enter downtown) — like this Patty Griffin mural from March, 2010. In recent months, though, he's had four panels in that space. For instance, here's a photo from two weeks ago, February 18:
JoePagac.com, the Ozomatli mural was signed Ed Muren III. This was the first work I'd seen of Ed's, but I've found another and I'll post it next: on March 6. (I'll also try to get downtown soon and see whether Joe has done all of the next batch of Rialto murals himself.)
