\u201cThat basically was the launchpad for my academic career,\u201d he explains in a video call with LedZepNews.<\/p>\n
A trained classical composer, heavy metal guitarist and professional audio engineer, Liu-Rosenbaum\u2019s approach sees him discuss every element of Led Zeppelin\u2019s music in forensic detail, rooted in music theory.<\/p>\n
\u201cI wanted to apply that kind of rigour to their music to try to understand why I liked it so much, because we were used to doing that with classical pieces,\u201d he explains.<\/p>\n
\u201cA lot of the time you never really get to the why of it. You talk about chords and rhythms and melodies and motifs and you can parse things into different pieces. But I\u2019m really interested in the emotion,\u201d he adds.<\/p>\n Now, he\u2019s written a book, \u201cSonic Narrative of Led Zeppelin\u201d, which uses the latest academic approaches to consider how Led Zeppelin\u2019s music is able to generate an emotional response in listeners.<\/p>\n In the 288-page book, which will be published by Bloomsbury Publishing on April 1, Liu-Rosenbaum discusses what he calls \u201cthe heroic quest for wisdom\u201d, something he believes is a narrative present throughout the band\u2019s discography.<\/p>\n \u201cThe lyrics of \u2018Stairway to Heaven\u2019 suggest something like that,\u201d he explains. \u201cBut also there\u2019s a sense of journeying, of wandering but also of seeking that I got through several Led Zeppelin songs.\u201d<\/p>\n \u201cEven in songs that I didn\u2019t write about, \u2018We come from the land of the ice and snow\u2019, there\u2019s this sense of travel. And travel also has an association of learning,\u201d he adds.<\/p>\n Liu-Rosenbaum\u2019s work is an exhaustive exploration of Led Zeppelin\u2019s music, covering everything from the tempo of the instruments and pitch of the vocals to the stereo placement of different sounds.<\/p>\n He hopes his book will be accessible to people outside of the realm of academic study of music. \u201cI said to myself, I\u2019m not going to do just a textbook. I did not want it to be a dry kind of purely analytical book,\u201d he explains. \u201cI made it so that it really skirts the line between textbook and fan book, because I\u2019m a fan.\u201d<\/p>\n Throughout his work, Liu-Rosenbaum closely analyses the lyrics of Led Zeppelin\u2019s catalogue, a topic he calls \u201cunderestimated and underappreciated.\u201d<\/p>\n \u201cWe really should pay attention to the lyrics,\u201d he says. \u201cI had come across some things in the literature where the lyrics are discounted: \u2018It\u2019s just the screaming and the sex and whatnot.\u2019\u201d<\/p>\n \u201cBut no, they wouldn\u2019t have gone as far as they did if it were just that. It has to be something more of a spiritual level. And I, of course, knew a little bit about Page\u2019s interest in the esoteric, but I didn\u2019t see it as a negative thing. I just saw it as another dimension to their music.\u201d<\/p>\n While other Led Zeppelin books delight in drawing tenuous links between the band\u2019s music and Jimmy Page\u2019s interest in the occult, Liu-Rosenbaum sticks to analysing what we actually know.<\/p>\n \u201cI didn\u2019t want the book to be another one of those \u2018let\u2019s try to find this evil subtext\u2019,\u201d he says. \u201cThere\u2019s enough of that. And frankly, the music never affected me that way. It lifted me up. And that\u2019s what I wanted to communicate to people.\u201d<\/p>\n Being a trained audio engineer, Liu-Rosenbaum also spends significant time analysing Led Zeppelin\u2019s studio methods.<\/p>\n \u201cI think that\u2019s maybe just second to the music itself,\u201d he says. \u201cThe way Page put his hand in the production process clearly guided the songs to some really interesting sounds.\u201d<\/p>\n As an example, he cites the technique in \u201cAchilles Last Stand\u201d where Robert Plant\u2019s vocals are doubled in alternate phrases in the song\u2019s verses.<\/p>\n \u201cThese are techniques that are compositional,\u201d Liu-Rosenbaum says. \u201cThat\u2019s basically composing with texture and timbre. Without that, the music would lose an entire dimension of meaning.\u201d<\/p>\n Led Zeppelin\u2019s studio innovation is a topic that he believes has often been overlooked. \u201cOne thing about Page and the band in general, they were really creative,\u201d he says.<\/p>\n \u201cWhen you talk about like progressive rock, people talk about Yes and other groups like that. But I think Zeppelin was really progressive when it came to production.\u201d<\/p>\n As well as analysing the sound of Led Zeppelin, Liu-Rosenbaum also considers the band\u2019s album art in his work. It\u2019s an approach he\u2019s nervous about.<\/p>\n \u201cI wasn\u2019t sure how people would take that, actually. Sometimes I\u2019m still afraid because the book hasn\u2019t come out yet. It\u2019s not finished, it hasn\u2019t gone through the proofing stages,\u201d he says. \u201cSo I wonder if they\u2019re going to call me a quack. Everybody has their little insecurities.\u201d<\/p>\n But the combination of the music and the artwork often helps to explain the meaning of the band\u2019s work.\u00a0<\/p>\n \u201cThe image inside LZIV, you have to take that into account because that alone hits you when you see it,\u201d he says. \u201cEven if you don\u2019t understand any of the lyrics, [or understand] just a few of them, they go deep.\u201d<\/p>\n \u201cThey hit you in a very kind of deep psychological part of you. And when you look at the image with the lyrics, I knew that there was a power there. And I just wanted to try to accurately describe what I was experiencing. And if it resonates with other people, so be it. And if not, also, then I\u2019ll just go out on a limb.\u201d<\/p>\n The approach of combining analysis of the music and artwork is one that is becoming increasingly popular. \u201cThis kind of polysensory musical experience is starting to make its way through academia. People are starting to look at all the senses when it comes to experiencing music,\u201d Liu-Rosenbaum says.<\/p>\n Liu-Rosenbaum says his book references the ongoing debate around the appropriation of black music by white groups like Led Zeppelin, but it isn\u2019t a topic he covers in detail.<\/p>\n \u201cWhen I was listening, actually, I was asking myself if I was going to talk about this question,\u201d he says. \u201cI was listening to some blues artists and I realised, \u2018hey, wait, this blues artist copied that blues artist, and that blues artist copied that blues artist, and then you have Led Zeppelin.\u2019\u201d<\/p>\n \u201cSo you have a whole chain, a succession of borrowing. And it is part of the tradition. I\u2019m not making an excuse for those who borrow without permission and without credit, obviously,\u201d he continues. \u201cBut I think that there needs to be a counterbalance to and a greater contextualisation of the question before we can really judge people so harshly.\u201d<\/p>\n After spending more than 20 years researching the music of Led Zeppelin, what might Liu-Rosenbaum have spotted that others have missed?<\/p>\n \u201cIt\u2019s presumptuous of me to say because I\u2019ve probably missed things that you all have heard,\u201d he says. \u201cIn general, we have a tendency to listen to rock and metal music and oversimplify it. People would say, \u2018Oh well it\u2019s just distortion. That\u2019s why it\u2019s powerful.\u2019 Or \u2018The lyrics are vague enough so everybody can associate to something in them.\u2019\u201d<\/p>\n \u201cBut there\u2019s a lot of nuance in the sound. A tremendous amount of nuance. Details that are definitely the result of intensive studio work,\u201d he says. \u201cI know because I am trained as an audio engineer in addition to being trained as a composer. And I worked as an audio engineer. So that gave me the tools to listen to this music from an audio engineer\u2019s ears.\u201d<\/p>\n \u201cWhen I first studied the mix to \u2018When the Levee Breaks\u2019 and I wrote it down on paper, I beheld in front of me the way the channels were clearly being swapped back and forth at the moment where I intuitively thought the levee broke in the narrative of the song, it clicked,\u201d he says. \u201cI said, no, this is composing with sound as well as music. And I would try to get that across to people in my book, that there\u2019s a lot to hear in the music.\u201d<\/p>\n Follow Led Zeppelin News on Twitter<\/a> and Facebook<\/a> to stay up to date on news as it happens.
