The Portland-based instrumental post-rock duo Talkdemonic will release their fourth album, Ruins, in October. The latest track off the album, the catchy "Revival," features very intense strings over an otherwise tight pop song. "'Revival' is a catchy pop-structured song, but with this wild viola solo flying over top,"violist Lisa Molinaro tells Rolling Stone. "String arrangements, shimmery synths and a solid bass lock it down, while the viola is allowed to go nuts." This unique sound was accomplished by "a lot of improvisation in the studio," Molinaro explains. Ruins will be in stores on October 4th, but you can download "Revival" for free here.
