exactly, recorded music is fairly new and kinda cheating (ynmv).....nothing like the spontaneity of live interpretations and improvisations imho...
Being able to play like it's fresh and spontaneous when recording is a skill on its own.
IMO some of the best recordings are played live in the studio (at least drums and bass) with overdubs to fix small mistakes and add to the sound. It's kind of like painting.
Consider how Led Zeppelin 2 was recorded. From the Bob Spitz book:
“It was quite insane, really,” he (Jimmy) recalled. “We had no time, and we had to write numbers in hotel rooms. We’d put down a rhythm track in London, add the voice in New York, overdub harmonica in Vancouver, and then [go] back to New York to do the mixing.”
The recording itinerary was indeed astoundingly peripatetic. At tiny Morgan Studios in North London, with Glyn Johns’s brother, Andy, at the board, they’d laid down the tracks for “Thank You,” “Livin’ Lovin’ Maid (She’s a Woman),” and “Sugar Mama,” the latter of which was eventually abandoned. “Heartbreaker” was recorded in New York, with the rhythm track taped at A&R Studios. Jimmy’s solo, however, “was an afterthought,” he said. “That whole section was recorded in a different studio”—farther uptown at Atlantic—“and was sort of slotted in the middle.” While at Atlantic, he put the finishing touches on “Bring It On Home,” which had initially been cut at funky R&D Studios in Vancouver. “Moby Dick” finally came together at Mirror Sound in LA, then back to New York for “Ramble On” at Juggy Sound before heading back to Olympic in London for a session that produced “What Is and What Should Never Be.”
“We recorded and overdubbed our way from West Coast to East Coast,” Jimmy said, gratified that they were able to pull it off. Miraculously, consistency wasn’t a problem, nor was what he called “the attack”—the way they bit into those songs “to get excitement onto a piece of plastic.” It was essential to match what was happening onstage—the dynamics, of course, but also the spontaneity and the experience. “Part of the excitement of the album is due to the fact that we were completely energized from the live shows and the touring.”
