Phish plays ACL Festival in 2010. Jay Janner/American-Statesman

The sharp (possibly glassy?) eyes at jambands.com tipped us off to a date from the kings of post-Grateful Dead jams, Phish, listed on the Austin360 Amphitheater’s calendar for July 28.

“While Phish’s Summer tour dates remain a mystery, one venue’s site has revealed that the band will be playing there this summer. Austin360 Amphitheater in Texas has listed a July 28 appearance from Phish,” the site for jam band fans writes. The amphitheater’s web site has no details on the show at this time and we have not received a press release.
