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.

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.

Following the first-ever U.S. vinyl release of The Replacements’ final album, 1990′s All Shook Down, on Record Store Day’s Black Friday later this month comes word that bandleader Paul Westerberg’s second solo effort, 1996’s Eventually, also will make its debut on vinyl early next year.

The Replacements staged their third of three announced reunion shows last night in a dusty farm field about 45 minutes east of Denver, the site of the third installment of this summer Riot Fest and what may or may not have been the final appearance by the 2013 incarnation of the ‘Mats, performing for the first time in 22 years.

The Replacements took the stage tonight at Riot Fest in Chicago for the second of at least three planned reunion gigs (“We haven’t played in 3 weeks, but fuck it,” Paul Westerberg told the crowd before launching into “Takin’ a Ride”), and managed to play mostly the same set as their big comeback gig.

A little after 8:45 p.m. EDT tonight, the long-sought, little-believed reunion of The Replacements — in this case, Paul Westerberg and Tommy Stinson, plus Josh Freese and David Minehan — took the stage at Riot Fest in Toronto, delivering career-spanning in the band’s first performance in 22 years.

We’re now just days away from The Replacements’ first live performance in 22 years, and the band — Paul Westerberg and Tommy Stinson plus, drummer Josh Freese and guitarist David Minehan — have teased fans with a third very brief live clip. This time we get 11 seconds of ‘Mats tearing through “Takin’ a Ride.”

With the long-awaited reunion of The Replacements now less than 10 days away, we’ve now finally got official word of who’ll be joining Paul Westerberg and Tommy Stinson on stage at Riot Fest in Toronto: drummer Josh Freese and guitarist David Minehan, both of whom played with Westerberg on his early ’90s solo tours.

A week after teasing fans with the first footage of The Replacements rehearsals now under way in Minneapolis, the ‘Mats today did a bit better, posting to Facebook 19 seconds of Paul Westerberg and Tommy Stinson ripping through “Favorite Thing.”

Here it is: The first footage, albeit just 9 seconds and shot through the sliding-glass door of a rehearsal space, of The Replacements, together again and performing in 2013. The band’s official Facebook page shared video of the ‘Mats running through performing “Alex Chilton.”

On Friday at its Solid Sound festival in Massachusetts, Wilco played a 27-song all-request set that featured exactly one Wilco song… and 26 covers by artists ranging from Television and Bob Dylan to even Daft Punk — not to mention The Replacements’ “Color Me Impressed” with Tommy Stinson.

The Replacements — namely frontman Paul Westerberg and bassist Tommy Stinson — will reunite on stage for the first time in 22 years later this summer to headline Riot Fest in Toronto, Denver and Chicago, site of the band’s unceremonious final performance in Grant Park on July 4, 1991.
