The latest side project from R.E.M. guitarist Peter Buck — the country-tinged Tired Pony, fronted by Snow Patrol singer Gary Lightbody — stopped by the ‘Late Show with David Letterman’ last night to perform ‘Dead American Writers,’ off the band’s just-released debut ‘The Place We Ran From.’

R.E.M. tonight posted a minute-long video of the band’s recent recording sessions in Nashville, showing, in typically enigmatic fashion, Michael Stipe playing high-pitched noises off some kind of contraption while the rest of the band and assorted personnel record a round of handclaps — after which Peter Buck asks, ‘Should we double track it?’

R.E.M.’s Peter Buck and Scott McCaughey joined Pearl Jam in Berlin last night to rip through the MC5’s classic ‘Kick Out the Jams’ at a concert that also featured the Seattle rockers debuting a new cover of Public Image Ltd.’s ‘Public Image.’

Word emerged this spring — via bandleader Colin Meloy’s Twitter feed — that R.E.M. guitarist Peter Buck would be contributing to The Decemberists’ upcoming sixth album — and we’ve now got photographic evidence, thanks to a series of snapshots posted on R.E.M.’s official site today.

R.E.M. will mark the 25th anniversary of their third album, ‘Fables of the Reconstruction,’ this summer with the third installment in the band’s ongoing reissue series, a double-disc re-release featuring 14 previously unreleased demos — including one never-before-heard song.

Attention tapeheads: The ever-iconoclastic Robyn Hitchcock is releasing an ultra-limited run of his new album ‘Propellor Time’ — on which he’s backed by members of R.E.M. and The Smiths — on ‘hand-assembled’ cassette.
