I've already bought my Austin City Limits Festival tickets, though there haven't been any announcments about the line up yet. I imagine that it will be a great time nonetheless.
Other than that, my summer concert schedule is fairly light. I'll probably swing to see John Mayer, and I'll check out local stuff, but other than that no real destination concerts. I've missed the Darkness, and David Bowie was a few nights ago. If Modest Mouse swings through, I'll check them out, and I'll keep an eye on pollstar, just in case...
ETA: According to Pollstar, the Pixies will be playing on Saturday at ACL. YAY!!! Amd they'll be in Houston on Claudia's birthday! Woo hoo!
