Personally I still like to have something tangible to look at when I'm listening to new music (even if like this it's not so new !!). The packaging is excellent (love the little pop-up of the band as per original vinyl release) and I already knew what I was getting was musically great. The sound is of good quality when you consider how long ago it was recorded but this album was to me more about feel than production, with a good rock/blues/folk feel and really accessible songs (not like later concept albums)
Later on Ian Anderson took the band on various adventures into different musical styles (all good in their own way......well nearly all.....when he used drum machines he lost my interest !) and the production really did take off then (or did it take over ?).
Anyway, to any real fan of Jethro Tull you should get this (as probably the third or fourth variant in your collection, like me) for the CD cover & sleeve notes, plus a good number of extra tracks which are all pretty good. When I saw that a DVD of their concert in Carnegie hall was also included I got momentarily very excited, then I read 'audio only' (and they meant it !). After the initial disappointment I did listen to it and enjoy that too.
To anyone who doesn't know the band well, but likes that late 60's early 70's rock genre, at least take a chance and buy a cheaper version of the album....it's really worth a listen.
