Not bad. It was more enjoyable than I had anticipated. On first listen it reminded me more of Heavy Horses than Thick As A Brick. The surround mix was excellent, as expected from Steven Wilson. In the liner notes IA states that SW would have liked inclusion of the saxophone, which was so integral to A Passion Play - the real sequel to TAAB - and it would have been a real treat to hear IA play the sax as well as the flute; but it didn't happen here.
I had also purchased at the same time the Live at Madison Square Garden 1978 concert on CD/DVD, which has DTS 5.1 sound, and it was even more enjoyable than TAAB2 as it had one of the best Jethro Tull line-ups at their peak. The 50+ minute video of the concert was fabulous, and the sound quality was quite good.
What I am eagerly looking forward to is TAAB1 been given the Steven Wilson treatment; followed, hopefully, by A Passion Play!
