Query: A difficult read

Unless you are both a music student/professor and a diehard Jethro Tull fan, I fear that like me you will discover this book is likely to be very hard going. Allan Moore is both and that style permeates the whole analysis of this 1971 breakthrough album by Tull.The interesting thing about the 33 1/3 series is how variable and eclectic the variety of writers are. The thing that hits one most about this specific book is that unless you really know the album inside out and Tull's greater musical history, you are hampered from the outset and the greater part of the book proves pretty unfathomable. Every song gets dissected with a musical surgery analysis that drains any desire to go and listen to the album further and the numerous footnotes to other books, articles and websites (including a fair number by the author) leaves you wondering if you have ended up in some heavy version of a music pseuds corner.One of the least enjoyable of the series I have read so far!
