"The Core" is a long up-tempo song, clocking in at nearly 9 minutes long. Clapton and Levy sing the vocals as a duet.
Something Else! critic S. Victor Aaron described the riff as "gritty".
Rolling Stone critic John Swenson described the song as having a "boogie rhythm reminiscent of
Derek and the Dominoes."
Potomac News critic Bren Bailey said that the song "allows Clapton and his band to explore just about every vocal and instrumental
blues experience known to man, and then some." The lyrics of "The Core" are about "self-motivation in times of difficulty" and is one of several Clapton songs that convey a message of faith. ==Reception==
