R.E.M. held their first “live rehearsal” in Dublin last night, previewing not only ten new songs but a set of mostly way-early stuff (“Second Guessing,” “Letter Never Sent,” “1,000,000,” “Little America,” “These Days,” etc.) The show intro and first new song have been Youtubed…hopefully there’ll be more to come. Update: Ah, that was quick. Just as I post this, many more quality videos surfaced, including Youtubes of new songs such as “Until the Day is Done,” “Living Well’s the Best Revenge,” and “Horse to Water.”
