The episode of ‘Austin City Limits’ featuring noise-rock mainstays Sonic Youth premiered this weekend, and now you can watch the whole thing online. The episode also features The Black Keys.

This week’s new releases include ‘Content,’ the first album of new material from Gang of Four in more than 15 years, and ‘Shot Live at the 100 Club,’ a CD/DVD chronicle of The Godfathers’ 25th anniversary concert in London last summer.

The playlist from tonight’s ‘Dark Wave’ — the Sunday night ‘darker side of alternative’ show on Sirius XM’s 1st Wave — features tracks by PiL, Kate Bush, Vicious Pink, The Smiths, Cetu Javu and more.

The University of San Francisco’s pioneering college radio station — KUSF, one of the first outlets to play punk rock and whose DJs are credited with helping break bands like Depeche Mode in the U.S. — was pulled off the air abruptly this week.

Another week, another song emerges off R.E.M.’s upcoming ‘Collapse Into Now’: This time, it’s track 3 off the album, ‘Überlin,’ which is being pushed as a single in Europe.

While punk rock is most closely associated with the London and New York City scenes of the late 1970s, the Los Angeles strain that erupted in the early ’80s was just as vital — something Dave Travis attempts to document in his forthcoming DVD ‘A History Lesson Part 1: Punk Rock in Los Angeles in 1984.’

The Pixies are keeping the ‘Doolittle’ train rolling, announcing this morning a new round of 16 North American dates this April and May that mostly will hit Canadian cities — but with stops in Detroit, Milwaukee and St. Paul, Minn. thrown in as well.
