Some of y’all sound like you’re musicians in your own right. I was just 12 years old when I fell in love with the Mighty Zep. I bought their vinyl & recorded the 2nd play of new vinyl on cassette, (Playing records while zooming along in a sports car very problematic even today.) Maxell did me right, I never needed a replacement tape, Also, thanks to Pioneer, JVC, & Yamaha for awesome recording equipment! I’ve got a couple hundred cassettes still in fine shape in 2020. Composition never comes easy unless you’re a certain 18th century guy name of Mozart. I’ve not tired of Led Zeppelin in 50 years because every time I’ve played them (cd’s since the 80’s, 90’s for cars) A Lot & every listen, be it a song or the whole album, brings differences to my ears. I’m a trained classical musician. So you tend to listen for differences among 4-10 melodic lines being played all at once. Led Zeppelin does the same thing as a roomful of musicians! Always different every time, even after 50 (!) years. I don’t go looking for collectibles or anything like that, I’ve just loved this group since being turned on to them. Well, I read books on them, I’ve kept a few. In the 90’s during music retail’s heyday, I worked for a good company as 1 of their top classical music sellers and also held the title of the resident Led Zeppelin guru. We were in the middle of the desert between San Diego & Austin. Not an easy job! With killer sales of all of Led Zeppelin’s catalog and lots of very different classical composers, we made a name for our shop. Only other rock bands I ever really noticed other than Led Zeppelin were Pink Floyd & ZZTop. Three of Rock’s best ever guitarists. Great for different types of playing. Page, Gilmour, & Gibbons bring their own unique flavors but all 3 have 1 thing in common, they “stay inside the song.” I have no idea how many times they rewrote the music or how many takes it took for them to record/mix a tune “Right!”, they did it. And I’m grateful to them! I think trained musicians bring different ideas about others’ work to the table over listeners. Training people how to listen to music is another factor in this equation. I was a premier competitor in car audio competitions in their heyday, also the 90’s. The best judges were like me, trained musicians, I guess you learn to listen when you’re part of a group of 3-50 people “making music.” Y’all’s takes on the Mighty Zep’s musical skills was interesting. But a little unexpected because it didn’t focus so much on the mechanical difficulties involved in songwriting before settling in to record them as it did focus on the inherent beliefs that these guys went into the studio with notes set in stone on a piece of paper! Different strokes for different folks . . .
