DULUTH, GA—Debuting yet another arrangement of the classic song Wednesday night, singer-guitarist Eric Clapton reportedly treated a sold-out crowd at the Gwinnett Center to an even slower, somehow mellower acoustic version of his original 1971 hit “Layla.” “When he played those first 45-second-long notes of the opening riff, that was when everyone recognized it as ‘Layla’ and just went nuts,” concertgoer Leslie Friedrich said of the 87-minute rendition, which according to listeners featured three eight-minute choruses and a half-hour jazzy piano interlude before concluding with a lengthy fadeout. “I heard those brushed drums and glacial tempo and my jaw dropped. I was like, ‘Wow, he actually managed to come up with a more lethargic and neutered acoustic jazz-blues version of “Layla” than ever before! How did he pull it off?’” Sources confirmed Clapton followed “Layla” up with a vigorous, electric double-time version of “Tears In Heaven.”
