Just back from watching Jethro Tull perform in Oxford having been dragged along by my wife who is a great fan of them. I had never listened to much of their stuff and found them to be an interesting mix of classical, folk and rock. My wife was a little disappointed with the singing but the real star of the show for me was the classical violinist Lucia Micarelli who was on stage with Jethro Tull for most of the show.
Purchased her CD "Music from a farther room" and listened to it on the way back.
