I'm a big tull fan. Especially from 71-79.
I think their best albums are in this order:
Thick as a brick(WOW), Songs from the Wood, Heavy horses, Warchild, Aqualung, Stormwatch, Broadsword and Minstrel..
I like some songs of their earliest 3 albums but their style isn't always appealing and Ian has yet ta mature his voice.
Some albums that are more obscure:
Too old to rockn'roll was a bit dissappointing. The are in excellent form, but somehow the music is not that catchy..
The A album(supposed to be a solo album A for Anderson, but the record company insisted...) wasn't that good at first but it grew on me.
Under Wraps: Ohh god... electro-cheese... but European legacy is a very good song.
Crest of a knave: Return to the folk-rock style. But Ian's voice has changed
Still an ok album
Rock Island and
Catfish rising: HAve those but I kind of give up everytime I listen to them..
Roots to branches is interesting: Very folky and exotic all way through. Not always catchy and too long songs but a good effort
J-Tull.com has it's moments like the title song.
I must mention Ian's solo album
Rupis dance(2003). I think it's his best work since Broadsword.
The secret language of birds (2000) is good also.
I went through a Tull phase when I discovered the band in 2005( Before I'd heard the name and the song Aqualung but that was it) and bought many of their albums.
Jehtro Tull/Ian Anderson are playing here next week. His voice is kind of ruined but it's still enjoyable to hear him play fantastically and tell jokes and move about. I think Tull and he playing solo now is quite similar( pretty much the same musicians).
