Nick Cave is 63 years old, and he’s one of the few artists of his generation who’s still making music that’s just as intense and vital and fearless as what he was doing when he was much younger. Thus far this year, Cave has teamed up with his Bad Seeds bandmate Warren Ellis to release the Carnage album, and he’s also come out with “Letter To Cynthia,” a one-off song inspired by a question from a fan. Today, Cave has announced plans to release a new collection of B-sides, rarities, and unreleased tracks that’ll cover a pretty great period of his career.
