There very well could have been a full-fledged R.E.M. reunion in Portland, Ore., on Saturday night as all four members of the defunct college-rock superstars performed after Peter Buck’s wedding. But, by all appearances, they managed to avoid such headlines, just barely, by not actually sharing the stage together.

The Dream Syndicate opens its second run of European reunion concerts tomorrow, but bandleader Steve Wynn already is thinking bigger, raising the possibility of recording new music with his old band with a very specific goal in mind: making the “missing” album to bridge the gap between its first two records.

Sad Lovers & Giants — who’ve earned a strong cult following despite having broken up and re-formed multiple times since debuting in the early ’80s — are in the studio recording what could be their first album in more than a decade, with enough songs currently in the works to comprise “70 percent of an album.”

The Breeders brought their Last Splash 20th anniversary tour to Boston for a homecoming gig Thursday night, but ended up celebrating an earlier era as co-founder Tanya Donelly re-joined Kim Deal and Co. onstage for a pair of numbers, including a giddy, laugh-filled cover of The Beatles’ “Happiness is a Warm Gun.”

Last fall, Kitchens of Distinction’s Patrick Fitzgerald and Julian Swales reunited for the first time since the dream-pop act folded in 1996, but they weren’t sure what to call the project. But now it’s official: With Dan Goodwin back on board, too, Kitchens of Distinction have just finished their first new album in 19 years.

The annual All Tomorrow’s Parties holiday festival in Camber Sands, England, will come to an end later this year with one final two-weekend extravaganza, with the first weekend headlined by Television performing Marquee Moon in full and the second weekend both curated and headlined by the reunited Loop.

The Call — best known for ’80s radio hits “The Walls Came Down,” “I Still Believe” and “Let the Day Begin” — reunited for the band’s first concerts in 20 years over the past two nights, performing in San Francisco and Los Angeles with Robert Levon Been of Black Rebel Motorcycle Club filling in for his late father.
