Turn A Gundam

Hello all,

I am looking for more info on this Gundam series/movie/whatever.
Specifically where I could find the piece of music called "Second Advent:
The Claws of God Strike at the Beach".  Our marching band is performing it
(with permission from Yoko Kanno and her agent) and I want to see the anime
to see how it fits together.  We are doing that and 5-6 selections from
"Escaflowne".  Any help would be appreciated.  Thanks in advance.
