Aqualung is one of the best albums ever but I wouldn't say it was ahead of their time.lots of great albums came out.black Sabbath in particular was kicking ass with their religion themed music at the time too.it was that era I guess.wish I was there.saw black Sabbath but still pissed I missed out on seeing Jethro Tull a few years ago.
saw Tull in late 70s, Ian Anderson running around like his hair was on fire, playing his flute like the Pied Piper leading the rats down to the waters edge...fucking killer!
