The makers of the forthcoming documentary ‘All For The Best: Songs of Mark Mulcahy and Miracle Legion’ this week posted an eight-minute ‘snippet’ of the nearly finished film online, a two-years-in-the-works project that includes interviews, vintage Miracle Legion footage and performances from a 2009 benefit concert.

Last week, Bob Mould ‘covered’ Sugar’s ‘If I Can’t Change Your Mind’ for The A.V. Club’s Undercover series. But before the song was crossed off the list, The Decemberists asked to do it, too. Watch that performance here.

Big Audio Dynamite rocked Lollapalooza over the weekend, and if you didn’t get a chance see Mick Jones and Co. on the live webcast — let alone attend the Chicago extravaganza — the festival has posted video of three songs from the band’s set.

Last night, the reunited Big Audio Dynamite returned to the American airwaves with a performance of ‘Rob Peter Pay Paul’ — the original lineup’s first new song in 21 years — on ‘Late Night With Jimmy Fallon.’

Saturday night, following an eight-year absence, MTV’s iconic alternative-music show ‘120 Minutes’ returned with a new format and a familiar face: late-’90s host Matt Pinfield. The whole show is now online; watch it here.

When Bob Mould stopped by The AV Club for its Undercover web series, the producers asked him to perform Sugar’s “If I Can’t Change Your Mind,” one of the few songs left on the current list.

This is a little more mainstream than what we usually cover, but it’s hard to deny the significance: Thirty years ago today, on Aug. 1, 1981, MTV went on the air (‘Ladies and gentlemen, rock ‘n’ roll…’), changing the course of music in the ’80s and beyond.
