"During the 6 years that Yellowcard was apart, I was constantly searching for ways to continue my career as a musician and producer, I had the idea to basically do Yellowcard covers featuring friends and artists I’ve had the pleasure of knowing throughout my career," explains Yellowcard vocalist/guitarist Ryan Key about "A Hopeful Sign", their new collaboration album with the Nashville-based post-rock duo HAMMOCK. The new album revisits some of the alt-rock band’s most unforgettable songs and revamps them with an ambient and delicate feel.
