Fans can now hear Eric Clapton's upcoming studio album in its entirety, one week before it's set to hit stores and digital retailers. 'Old Sock' will feature 10 covers and two originals when it's available on March 12. It's Clapton's 21st studio album.

The Wall Street Journal's Speakeasy Blog is streaming the album. It's a fan's first chance to hear Clapton's take on Leadbelly's 'Goodnight Irene' and Taj Mahal's 'Further on Down the Road.' In addition, one will find 'Every Little Thing,' a bluesy love ballad written just for 'Old Sock.' Clapton previously revealed the other new track 'Gotta Get Over.'

Guests on the album include Paul McCartney playing bass on 'All of Me,' Steve Winwood on organ for 'Still Got the Blues' and JJ Cale lending his vocals to 'Angel.' The project covers a wide variety of genres, including songs by Peter Tosh and George and Ira Gershwin.

Clapton's spring tour begins in Phoenix, Ariz. just two days after the album's release. The jaunt across the United States ends with two shows in New York City, the two-day Crossroads Guitar Festival at Madison Square Garden.
