Post Malone is no stranger to genre-bending collaborations, teaming up with everyone from Ty Dolla $ign and 21 Savage to Ozzy Osbourne and Justin Bieber for chart topping hits. But the singer almost dipped his toes into the indie rock pool recently.

In an interview on RADIO.COM’s New ArrivalsFleet Foxes singer Robin Pecknold revealed that the band almost collaborated with Post on their recent album, Shore. “He came by the studio for one day while we were working in L.A. and listened to stuff and was super supportive,” he said. “We didn’t get together in time because I wanted to get the album out quickly, but I did ask him to be on it. He was down, but we just didn’t end up having time.”

Post Malone’s been a longtime fan of Fleet Foxes; he even tweeted out a declaration of love back in 2015. “if you don’t like flee [sic] foxes then f— you,” he proclaimed.
