I saw Jethro Tull in concert a couple of years ago. The Chieftans opened for them. It was a great show.
You must have heard Tull perform some songs from their latest studio album DOT COM. It's a very good cd with some great guitar riffs and solid melodies like Hunt by Numbers, Wicked Windows, Black Mamba, Gift of Roses, El Nino and of course Ian's beautiful flute on the title track.
Tull will be kicking off another American tour next month. I'll try to check them out down in Fort Lauderdale when I visit Florida. Ian is still not too Old to Rock'n Roll 26 years after releasing the album by that name..
