It’s beginning to look like The Replacements have a new member: Tonight in Atlanta, the band once again enlisted Green Day’s Billie Joe Armstrong, who first joined the band at the second weekend of Coachella last month, and now followed that up by appearing with the ‘Mats at the Shaky Knees Music Festival.

The Replacements’ reunion train continues to roll on, and now will hit the Pacific Northwest late this summer as Seattle’s Bumbershoot this week announced its 2014 lineup, which will feature the ‘Mats, Elvis Costello, Mission of Burma, The Afghan Whigs, Jonathan Richman, The Dream Syndicate and more.

Plain Recordings continues its run of 180-gram Paul Westerberg reissues, announcing this week that it will follow up its new editions of 14 Songs and Eventually with the release the once and current Replacements frontman’s third solo album — 1999’s Suicaine Gratification — on vinyl for the first time ever this fall.

Finally. It’s taken more than a year, but reunited college-rock icons The Replacements finally will play a hometown gig this September, as the band has been announced to headline the soon-to-be-razed Midway Stadium in St. Paul, marking the first Twin Cities appearance by the ‘Mats since 1991.

This is almost becoming a regular occurrence: Newly reunited college-rock legends The Replacements have been confirmed for their second festival appearance in as many days this morning at Boston Calling rolls out the lineup for its Sept. 5-7 extravaganza.

Like OutKast, reunited college-rock legends The Replacements seem content to stick strictly to festivals, the latest of which is the just-announced two-weekend Austin City Limits Music Festival in October, where the ‘Mats will join headliners Eminem, Pearl Jam, Skrillex, Beck and, of course, OutKast on the massive bill.

Coachella’s second weekend is under way now, and The Replacements took the stage tonight for the second of the reunited band’s appearances at the two-weekend fest — and dropped a big surprise on the crowd, as Green Day’ Billie Joe Armstrong joined the ‘Mats for part of the band’s set.

The schedule for the webcast of the first weekend of the Coachella festival — running this Friday through Saturday — features a number of great acts, including Bryan Ferry, Pet Shop Boys, The Afghan Whigs, The Cult, Fishbone, the just-added Pixies and more.

Since reuniting last summer for their first shows in 22 years, The Replacements have been nothing if not cagey about their intentions, and that continues with the band’s posting on Facebook this afternoon of an unexplained 12-second clip of “Can’t Hardly Wait” being performed live in an undisclosed recording studio.

It’s perhaps not surprising that The Replacements’ reunion has been a ramshackle affair, with the band playing three festivals last year, and, at this point, slated to perform five more times this spring and summer. To hear bassist Tommy Stinson tell it, that may continue for a while.

The Replacements reunion returns to Canada — where it began — this summer with a just-announced appearance at the Osheaga Music Festival in Montreal, just the latest in what continues to be a festival-only affair for the reunited ‘Mats. The band joins Nick Cave & The Bad Seeds at the Aug. 1-3 festival.

The Replacements reunion continues to be a festival-only affair, with the band following up three Riot Fest dates last year and two upcoming Coachella shows with an appearance this May at Atlanta’s Shaky Knees Music Festival, where they’ll share the bill with fellow reunion act Violent Femmes.

The Replacements reunion will roll on this year, with the band confirmed tonight to perform at the Coachella Valley Music & Arts Festival this April along with Pet Shop Boys, The Afghan Whigs, Brian Ferry, The Cult, Toy Dolls, Fishbone, Bad Manners, Neutral Milk Hotel and more — plus headliners OutKast, Arcade Fire and Muse.
