<human>: Recognizing Dylan's dissatisfaction with the progress of the recordings, producer Bob Johnston suggested that they move the sessions to Nashville. Johnston lived there and had extensive experience working with Nashville session musicians. He recalled how Dylan manager Albert Grossman, was hostile to the idea: "Grossman came up to me and said 'If you ever mention Nashville to Dylan again, you're gone.' I said, 'What do you mean?' He said, 'You heard me. We got a thing going here'". Despite Grossman's opposition, Dylan agreed to Johnston's suggestion, and preparations were made to record the album at Columbia's A Studio on Nashville's Music Row in February 1966.  In addition to Kooper and Robertson, who accompanied Dylan from New York, Johnston recruited harmonica player, guitarist and bassist Charlie McCoy, guitarist Wayne Moss, guitarist and bassist Joe South, and drummer Kenny Buttrey. At Dylan's request, Johnston removed the baffles--partitions separating the musicians so that there was "an ambience fit for an ensemble". Buttrey credited the distinctive sound of the album to Johnston's re-arrangement of the studio, "as if we were on a tight stage, as opposed to playing in a big hall where you're ninety miles apart". Dylan had a piano installed in his Nashville hotel room which Kooper would play to help Dylan write lyrics. Kooper would then teach the tunes to the musicians before Dylan arrived for the sessions.  On the first Nashville session, on February 14, Dylan successfully recorded "Visions of Johanna", which he had attempted several times in New York. Also recorded was a take of "4th Time Around" which made it onto the album and a take of "Leopard-Skin Pill-Box Hat" which did not.  On February 15 the session began at 6 p.m. but Dylan simply sat in the studio working on his lyrics while the musicians played cards, napped and chatted. Finally, at 4 a.m., Dylan called the musicians in and outlined the structure of the song. Dylan counted off and the musicians fell in, as he attempted his epic composition "Sad Eyed Lady of the Lowlands". Kenny Buttrey recalled, "If you notice that record, that thing after like the second chorus starts building and building like crazy, and everybody's just peaking it up 'cause we thought, Man, this is it ... This is gonna be the last chorus and we've gotta put everything into it we can. And he played another harmonica solo and went back down to another verse and the dynamics had to drop back down to a verse kind of feel ... After about ten minutes of this thing we're cracking up at each other, at what we were doing. I mean, we peaked five minutes ago. Where do we go from here?" The finished song clocked in at 11 minutes, 23 seconds, and would occupy the entire fourth side of the album.  The next session began similarly--Dylan spent the afternoon writing lyrics, and the session continued into the early hours of February 17, when the musicians began to record "Stuck Inside of Mobile with the Memphis Blues Again". After several musical revisions and false starts, the fourteenth take was the version selected for the album. CANNOTANSWER
