The Scottish synth-pop band reinterprets a beloved Tegan and Sara classic, premiering exclusively on EW

You won’t regret hearing this, this thing that they’re playing.

Scottish synth-pop group CHVRCHES are taking on the beloved Tegan and Sara classic “Call It Off” for The Con X: Covers, a tribute album that celebrates the 10th anniversary of the duo’s seminal LP, The Con. Bleachers, Ryan Adams, Paramore’s Hayley Williams, Sara Bareilles, and others have contributed to the collection, due Oct. 20. Net proceeds from the album will go to the Tegan and Sara Foundation, which “fights for health, economic justice, and representation for LGBTQ girls and women.”

“Lauren [Mayberry of CHVRCHES] was one of the first artists we approached for The Con X: Covers project,” Tegan Quin tells EW of the track, which is premiering exclusively on EW. “We are massive fans of CHVRCHES and the music they make. Lauren is an ally to the LGBTQ community and has been outspoken and political, so she fit the ethos of the project perfectly. CHVRCHES are in the studio making a new record, so we were touched they made the time to cover ‘Call It Off.’”

Fans of the original song might not recognize CHVRCHES’ version, however. Mayberry & Co. took the short and sweet acoustic number and stretched it out into a ghostly, five-minute keyboard daydream. “Their cover could not have been more unexpected and we think it’s beautiful,” Tegan says. “Our hope was that each artist would reinvent and reimagine each song, and they did not disappoint!”

The covers album arrives the same day that Tegan and Sara kick off The Con X: Tour, which will feature stripped-down arrangements of every song from the album, played in order, in addition to other songs from the band’s extensive catalog.
