An orchestraited version of Aerith's Theme, or Aeris' Theme, whichever name you prefer, from Final Fantasy VII
I went to the concert in Grand Rapids, and I can honestly say it was one of the greatest experiences I've ever had. Sadly, To Zanarkand, Dear Friends, Ronfaure, and Terra's' Theme didn't make it onto the CD. We can only hope they will be included in a second CD or some such.
Fun Trivia: During the concert, we got to cast votes between five battle songs we'd want added to Distant Worlds. Fight With Seymour won third place. Close but no cigar.
