Sonic Youth wrapped up a short South American tour last night with a 70-minute set at the SWU Music & Arts Festival in Sao Paulo, Brazil — something that normally wouldn’t be particularly newsworthy, except that it might have been the legendary noise-rockers’ final performance after 30 years together.

Here’s a nice bit of not-so-vintage video: A full 80-minute, 26-song Pixies concert filmed in Boston in 2004 for broadcast on HDTV as the special “Pixies Come Home: Live From their 2004 World Tour.” Thanks to the Pixies themselves for sharing the video on the band’s official Facebook page yesterday.

Now that he’s unemployed, former R.E.M. frontman Michael Stipe has plenty of time on his hands, which might explain his drop-in at the end of Thursday night’s ‘The Colbert Report.’ Stephen Colbert paid fitting tribute to ‘legendary rockers The R.E.M.s,’ then permanently enshrined Stipe on his ‘rock ‘n’ roll shelf of fame.’

If you caught the ‘Late Show with David Letterman’ last night, you may have seen Peter Gabriel perform his classic ‘Red Rain’ backed by the New Blood Orchestra. However, he also performed a full hour-long concert from the Letterman studio that was webcast, which you can see here.

Long known for their supermodel-filled ’80s videos, Duran Duran takes it a step further in their new nine-minute, Jonas Akerlund-directed “short film” for All You Need is Now single “Girl Panic!” by casting Naomi Campbell, Cindy Crawford, Eva Herzigova and Helena Christensen as the band’s members.

The Mike Peters-fronted Big Country is commemorating its U.K. comeback tour earlier this year with a collection called ‘Dreams Stay With You: Live 21st April 2011,’ a full 19-track performance spread across two CDs and two DVDs — and which you can preview via a clip of the show-closing ‘In a Big Country.’

Al Jourgensen not only has reactivated Ministry for a new album and tour next summer, but he’s decided to chronicle the recording of the ‘Relapse’ record with a series of short ‘webisodes,’ the first of which can be watched here. The album is due out in spring, with a limited number of U.S. dates next summer.

R.E.M. today released not one but two music videos for its new, and likely final, single ‘We All Go Back To Where We Belong’ — one featuring actress Kirsten Dunst, the other performance artist John Giorno. Both, shot in black and white, simply show a close-up of the face of their subject set to the new single.

Eagle Rock Entertainment is teasing its upcoming Talking Heads live DVD and Blu-ray — the 18-track ‘Chronology,’ spanning 1975 to 1983 — with this rare, early performance of ‘Psycho Killer,’ filmed at New York club CBGB in 1975. The collection will be released Nov. 21.

In honor of John Peel Day — during which we honor the legendary U.K. DJ/tastemaker on the anniversary of his passing — we present this hour-long documentary, ‘Turn That Racket Down,’ about the life and influence of John Peel that aired on the British television in the late 1990s.

With their fourth album, ‘The Great Escape Artist,’ arriving in stores today, Jane’s Addiction — Perry Farrell, Dave Navarro, Stephen Perkins and Chris Chaney — hit the ‘Late Show with David Letterman’ last night to deliver the record’s opening track, ‘Underground.’

For U.S. fans, the U2 documentary ‘From the Sky Down’ doesn’t premiere until this coming weekend — it’s on Showtime on Saturday night — but since it already aired in the U.K., intrepid fans like u2opia100 have uploaded the 84-minute documentary about the making of ‘Achtung Baby’ to YouTube.

David J is poised to release a new solo album called ‘Not Long For This World’ — featuring new songs and covers of tracks by Smog, Ed Harcourt, Tom Waits and Dennis Wilson — and he’ll revisit his Love and Rockets tenure by playing two California shows next week with tribute act Luv’n Rockets.
