Tull's early albums rank up there as all time favorites - This Was, Benefit, Aqualung, Thick as a Brick, Living in the Past...
They jumped the shark in the late 70s with Songs from the Wood etc. Had a bit of a rennaisance in the early 90s. That Grammy was more of a lifetime acheivement award.
The first concert I ever went to was Tull's War Child tour, at the Falls Convention Center, 1975.
