Last year's tribute concert to R.E.M., which featured the debut of the mysterious Elephant 6 conundrum called the Observatory (fronted by Bill Doss, but featuring various members of Olivia Tremor Control, Of Montreal, and other E6/Athens bands), is now up for pre-order at the AthensMusic site. At 19 tracks, the release from Iron Horse Records features three from the Observatory performance, while the others are by Liz Durrett, Tin Cup Prophette, Patterson Hood of Drive-By Truckers, and more. The official release date is May 29, but pre-orders will ship around March 20, so there's incentive for you. You can also buy posters and tee-shirts from the event at AthensMusic. Not on the CD, but released as part of the R.E.M. fan club Christmas album, is an Observatory cover of "These Days." You can download that through our site:
