1992’s Unplugged sold more than 19 million copies worldwide and won six GRAMMY® Awards, including Record the Year and Album of the Year. In 2013, Eric Clapton, touring in celebration of his 50th year as a professional musician, released a remastered version of Unplugged, including an essential deluxe version that adds six bonus tracks, rehearsals, and several songs not featured on the original album. Early versions of “Circus” and “My Father’s Eyes” (in two takes) precede their appearance on 1998’s Pilgrim. A cover of Big Maceo Merriweather’s “Worried Life Blues” and alternate takes of Jerry Lynn Williams’ “Running on Faith” and Robert Johnson’s “Walkin’ Blues” fill out the extras. This expands a great album, where there’s no such thing as too much of a good thing. The acoustic reworking of “Layla” remains the centerpiece of the original disc, with “Tears in Heaven” (originally recorded for the Rush soundtrack) the emotionally resonant timepiece. (It was written, with Will Jennings, about Clapton’s pain and suffering after the death of his four-year-old son Conor.) Timeless means timeless.
