Largely composed of cover songs, Old Sock contains tight takes on J.J. Cale cuts like "Angel" and blues-folk classics like "Goodnight Irene," but Clapton sounds especially fresh on his interpretations of old pop standards. His version of "All of Me" is playful, coyly subverting its lyrics about devastating heartbreak, and on his piano-based arrangement of the Gershwin ballad "Our Love Is Here to Stay," his voice sounds both grateful and wise, as if the romance he's describing has only gotten sweeter with time.
