On writing one book before you can write another

I’m going to soon start working on a book proposal for a book about a band I deeply, deeply love. And what I’ve realized as I’ve started taking notes on it is that I have to finish Dancing about Architecture.... before I can even conceptualize this book. I have to have answered the question for myself of how and why to write about music one loves*. 

The thing is, my approach to this hypothetical next book might actually end up being different than the answers I come up with in this hypothetical current book. All this stuff I’ve been saying about love, and about personal mythology or writing about art as a subjective act of autoethnography or whatever -- it might not fit. There are truly some big ideas I want to tackle in potential rock book #3, not simply intersections between subjective experience and the music itself, but how subjective experiences of art are influenced by and influence larger society-wide ideas, ideologies, and discourses. Maybe that’s not too far away from DAAIARTTD...but I don’t know yet. Because there’s more to write. Of making many books there is no end....

* I also have to answer the question that I raise somewhere in the manuscript about the fan-critic-artist relationship, but in a real way: what should my actual human relationship, if any, be with the people who comprise the band that I intend to write about? Do they as humans even enter into it, or is it just the Stuff that matters? Is the band More or even mainly Other than the middle-aged white guys who play(/ed) in it?
