Richard Reed Parry is best known as a core member of Arcade Fire. His classical solo album, Music For Heart And Breath, comes out July 15.Guillaume Simoneau / Deutsche Grammophon NPR | Staff Richard Reed Parry is famous for making music sound big. As a core member of Arcade Fire, the Grammy-winning indie rock group from Montreal, he wields multiple instruments to help create deep, layered textures in which strings and synthesizers, slow ballads and disco dance tracks are all at home. Parry's first solo album is a departure even from that broad sound. It's a collection of classical compositions featuring Nico Muhly, the yMusic ensemble and the Kronos Quartet. The album is called Music for Heart and Breath, and as Parry tells Weekend Edition Sunday, the title advertises the daring concept that holds the album together: the musician's body as metronome. "Every note, and everything that any of the musicians plays, is played either in sync with the heartbeat of that player, or with their breathing, or with the breathing of another player," Parry explains. "You have a stethoscope and you have an Ace bandage. The Ace bandage is wrapped around your chest, and it presses the stethoscope to your heart."

"It's definitely an un-intuitive way of playing music," he says. "Which is funny, considering that it's in some ways it's the most intuitive musical reference point that anybody could have."
