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 Pet Shop Boys brought their current Electric production to Coachella this past weekend for the first of two appearances at the California festival, delivering a 19-song set over the course of 80 minutes that was heavy on visuals, as is to be expected from the duo.

Having performed Blondie’s “Heart of Glass” at a pair of tour stops last week, Arcade Fire added a special treat during its Sunday night headlining set at Coachella: Debbie Harry herself, who joined the band to sing the 1978 hit. The Blondie frontwoman stuck around for “Sprawl II (Mountains Beyond Mountains).”

Ten years ago, the Pixies used Coachella to formally launch their comeback, so it’s fitting the band returned to the festival this weekend as a very late addition, playing a 15-song, 50-minute set that featured old favorites and a handful of tracks that will be included on upcoming album Indie Cindy.

The Cult took to the stage at the Coachella festival late into the evening on Friday, playing an 11-song, 50-minute set that drew on classics (“Love Removal Machine,” “Rain,” “Wild Flower,” “She Sells Sanctuary”) as well as newer material recorded in the last few years.

With the reunited Afghan Whigs set to release their first new album in 16 years on Tuesday, it’s no surprise they dedicated half of their 10-song, 40-minute set at Coachella on Friday to material from Do To The Beast. Below, you can see a rip of the full webcast of the Whigs’ performance.

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.

The Jesus and Mary Chain — who performed live just a handful of times last year — have been confirmed for their first show of 2014 as organizers of the Cultura Ingelsa Festival in Sao Paolo, Brazil, announced this week that the brothers Reid will close out the the 18th annual music fest on May 25.

The Cure will return to North America late this spring to headline the BottleRock festival in Napa Valley, Calif., joining, at the top of the bill, OutKast, Eric Church, The Fray, Weezer and Band of Horses — plus Camper Van Beethoven and Cracker.

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.
