I have nearly every album on either vinyl, cd or both, can't even remember the sonics since I haven't listened to them in so long. Happy to see this posted, have to include them in this weekend's listening sessions. Its all good, although the earlier the better for me. The critics nearly always hated them, used to call them Jethro Dull. It may have been Ian Anderson pissing off the press, he reportedly had a condescending attitude towards them.
Also saw them live back in 73, just after Passion Play was released, great concert. Ian Anderson was a madman on stage, a menacing presence. I remember pre-concert, this huge projection screen with the dancer from the cover of the Passion Play album. The lights in the house up, talking to friends, whatever, look up at the screen and you swear the dancer moved. You then watch the screen and the dancer moves just the slightest perceptable bit, over a period of fifteen, twenty minutes each movement slowly picks up in pace until just prior to them coming out on stage the dancer is moving in real time. Probably doesn't sound all that impressive, but having smoked a lot of that sweet stuff made it strangely surreal.
