Jethro Tull...any cd's to stay away from?


I recently realized that while I have several lp's I don't have any cd's by Tull. Really like the early stuff. The difference between some originals and remastered material has also been a recent revelation to me and not looking to waste any $$ on cd's I'll not play more than once what and where would you look? What about the quality of the dvd concerts?

Regarding the Aqualung cd.....I have read that a Capitol-EMI release was of decent sound quality(as compared to Chrysalis). I found 2 related to EMI...one is EMI UK and the other is Toshiba EMI from Japan. Are these 3 related/the same? Or maybe I guess I should probably just get my turntable fixed and play my old albums.
Ian stated Tull recorded Aqualung at the same place and time Led Zep recorded their fourth album and they had the large studio and Zep had the small cramped studio in an old converted church. The rest is history.
The Live Aqualung sounds pretty good. it was done for a benefit. pretty easy to find.
After reading this thread, will have to get out my Heavy Horses LP for a listen...have Aqualung on cassette that was recorded off the radio and it sounds pretty good, probably recorded from a cd...
