Yep. Pictures At Eleven and Principle of Moments are my "favorite album". The reason I use the singular is because I see the two albums as two sides of the same coin. One side, Pictures At Eleven, is the more basic rock style and the other side, Principle of Moments, is more sophisticated. I LOVE the albums and I don't think Robert ever did anything like it ever again.
Shaken n' Stirred is a bit weak apart from Too Loud, Little By Little and Sixes and Sevens which is amazing.
Honeydrippers is really great. I listen to it a lot and the special guest appearences from Jeff Beck and Jimmy Page are brilliant. I even have the original Es Paranza tape from '85.
Now and Zen, apart from The Way I Feel, Heaven Knows and Ship of Fools, is PATHETIC! I heard Jimmy Page frizbeed it out of the window when he first heard it or was that just a wild unfounded rumour?
Manic Nirvana is OK.
Fate of Nations has some magic moments (Maire Brennan, among others).
I sort of lost track afterwards until Raising Sand which is really beautiful.
But back to the first two. If you love those albums as much as I do, try to get the King Biscuit Flower Hour show which is really brilliant. It was even used for the bonus tracks of the 2007 reissues. Fat Lip specially is brilliant! It's easy enough to find on the net. It's out there. Nudge, nudge, wink, wink. ;-)
