The May 29 date was announced this morning on the Denver Post's blog, which also notes that the former Sub Pop band's Columbia debut, Port of Morrow, will be released by in March.
In case you missed it, you can read a 2010 Indy interview with Shins frontman Mercer here.
While most of the summer bookings for the amphitheater have yet to be announced, other scheduled shows for 2012 include Flux Pavillion, Eric Church, Big Head Todd and the Monsters (sharing a bill with the Barenaked Ladies), and the obligatory John Denver tribute. Dates and details at the Red Rocks website.
This year also marks the first time the outdoor venue has held a winter show, with Atmosphere headlining a sold-out Jan. 27 gig. The evening before, the Minneapolis hip-hop group dropped by to perform an impromptu set at the less frosty Ogden Theatre, right before Colorado Springs' own ReMINDers hit the stage.
And yes, you can go here for the Indy's 2011 Atmosphere interview.
