I think Layla has been overplayed, and so there's now a tendency to be overly judgmental of it perhaps. It never comes close to bringing tears to my eyes anymore. I think if Duane had lived long and somehow had done lots of solos in their very vein, and the airwaves had been saturated with slight variations of this, we'd have burned out on this approach. But this is ONE song, one recording and I think Allman's part conveys precisely what is called for in the circumstances. I found, of the guitar parts Duane recorded over time, a lot of variety, and so I am satisfied he gave the engineer and producer what they asked for. The guitar part is meant to be unsettled, and overwelling with passion - it would seem wrong for it to be muted and more pitch perfect. + Compare this to Jerry Garcia. Jerry, sadly, tended to be pitchy more often than not, in this range. Many songs, many many different recordings, conveying all sorts of moods and themes. Not just one recording. I was slow to notice since the Dead got much less airplay, but the more I listened to Grateful Dead recordings, the worse it got for me and yet, the worst thing is now that other guitarists are playing Jerry's parts. And they have "fixed" them as to pitch and suddenly I am really enjoying the new renditions.
