Adams, wearing a Black Flag Slip It In shirt, handled lead vocals on the Heartbreaker track, with Mayer providing background on the rousing chorus and expansive guitar solos straight out of his work with Dead & Company. (Mayer will rejoin the Grateful Dead offshoot this summer for a 19-date tour.)
Mayer has been on the road to support his new album The Search for Everything, which arrived in full on April 14th after initially trickling out in "waves."
"It's beyond a break-up record," Mayer told Rolling Stone of his new LP. "It's about my impression of loss. It's about the ghost in the room. Proudly, it is, as my therapist says, a study into the metaphysics of absent love."
