Jethro Tull questions...

I don't know much about this groups' discography, only the songs played on classic rock radio.

I am not really interested in purchasing a greatest hits compilation. I would like to purchase the separate CDs, but I would like some feedback as to how their CDs sound.

I tried to find a remastered version of "Aqualung" but apparently only the gold disc exists and it usually can be found on Ebay for hundreds of dollars.

So my question is, do Tull plan on remastering this album?

Also, what about War Child, Benefit and Thick as a Brick?

Are there remastered versions of these albums available and how do they sound?

Thanks very much in advance.
