Whoops, it was a few days ago. Nuts, I'd have liked to see that.

Ian Anderson Plays Orchestra Jethro Tull w/ the Traverse Symphony Orchestra
Founding member of the rock band Jethro Tull, Ian Anderson has long been considered the foremost exponent of rock-style flute. While continuing to lead his legendary band in sell-out performances throughout the world, Ian Anderson now brings his acoustic talents to the orchestral stage. He will perform a selection of Tull favorites, solo songs and instrumentals, all carefully rearranged for amplified flute, acoustic-rock trio and orchestra. Tull fans will recognize such classics as "Aqualung," "Locomotive Breath" and "Bourée," interspersed with varied pieces, past and present.

Last time I saw Tull was 1988 or so. It was awesome. I better see them again before Anderson kicks the bucket.
