Jethro Tull - Nothing is Easy: Live at the Isle of Wight 1970 - CD
I've never really listened to Jethro Tull, except for stuff that comes on the radio. All I have to say after listening to this one is "wow!" I wish all music could be as free-flowing as this. The drummer on this is amazing, too.
I realize this is not Jethro's most important album, but it was the only one I could find on my digital music service.
