August 21, 1967: Recording session for Taj Mahal’s first album ‘Taj Mahal’. Jesse Ed Davis plays electric slide guitar on ‘Statesboro Blues’.

“I had never really played bottleneck before that,” Davis explained in Guitar Player, “and so for that recording I just put a steel tube on my finger and worked up a line. I just played it in regular tuning. I didn’t know about open tunings until I saw Muddy Waters play at the Whisky in Los Angeles some time after that.
