What more can I say? ( Okay, I will say a bit more...) This is my all-time favorite piece of rock music. Even better than The Who's masterpiece Tommy. A masterful composition musically and lyically by Ian Anderson, and his then-bandmates of Martin Barre ( the only one still playing with Anderson in what is still being called "Jethro Tull") John Evan, Jeffery Hammond and Barriemore Barlow brought the whole thing to life in one breathtaking two-sided ( back when it first came out on LP ) 45-minute song that still brings chills up and down my spine. I saw Tull only once in my life, and it was the 1972 tour when they played the entirety of this album - and then some, extending the 45 minutes into an over two-hour performance. What a show! And who has ever given enough credit to keyboard player John Evan on it? Man, his Hammond just rolls all the way through this song, dominating the soundscape much more than the guitar playing of Barre ( whose playing is of course superb nonetheless ). And with old friend Barriemore Barlow becoming Tull's new drummer on this album all the pieces were finally in place for the best and most fruitful lineup Jethro Tull ever had. All these guys were the best rock musicians of their time. It's too bad that Ian, Martin and a bunch of stand-ins still go around calling themselves Jethro Tull. In my mind Jethro Tull was Ian Anderson, Martin Barre, Jeffery Hammond-Hammond, John Evan and Barriemore Barlow - period. And their undisputed masterpiece is Thick As A Brick.
