Old Sock includes two new compositions ("Gotta Get Over" and "Every Little Thing"), and covers of some of his favourite songs from childhood to the current day. Several notable musicians were involved in the album, including Steve Winwood, JJ Cale and Paul McCartney. This is Cale's final major recorded contribution before his death in July 2013. It reached No. 11 in the UK Album Chart and No. 7 in the U.S.

Clapton previously considered naming the album 50 Years of Drift in an Open Tuning, a homage to the Derek Taylor book 50 Years Adrift (In An Open Necked Shirt). He was inspired to name the album Old Sock from a conversation with David Bowie. After hearing Bowie's then-new song "Where Are We Now?", Clapton sent a note thanking him "for writing such a beautiful song". Bowie responded, "Thanks for the shoutout, old sock. Really appreciate it." Bowie allowed Clapton to use the phrase for his album title and share the story of their conversation. Following Bowie's death in 2016, Clapton wrote "Sweet dreams old sock" on his Facebook account.
