III/IV

III/IV is the twelfth studio album by Ryan Adams, released on December 14, 2010. The album is his fifth with backing band The Cardinals. A double album, III/IV was recorded prior to bassist Catherine Popper's departure, and also marks guitarist and backing vocalist Neal Casal's recording debut for the band.

The album's title stems from "the idea that Cold Roses is volumes one and two, and this was a logical step that the Cardinals had taken forward as a band effort. The tracks shared the democratic process of a band. It will always be an amazing look into the world of a great band during one of its most versatile line-ups."
