In 2007, R.E.M. spent five nights with fans in a Dublin theater, test-driving songs for last year's Accelerate. This two-CD/one-DVD document captures intimate, occasionally great performances; if Michael Stipe sometimes sounds like he's reading lyrics off his computer, it's because, well, he actually was. Besides several solid Accelerate outtakes, the selling point on Live at the Olympia is R.E.M.'s spelunking through early catalog gems, when Stipe's vibrato-seizure vocals and Rorschach-blot "lyrics" clung to songs exploding at the seams. The stitching is tighter now, and drummer Bill Rieflin often holds things together too neatly. But when songs fray — see "Harborcoat" — it's the sound of imperfection perfected.
