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.
