Over the Sky contains both vocal tracks and orchestral pieces, performed with delicacy by The Warsaw Philharmonic Orchestra and Chorus, from the TV series. This is not just some CD called "Over the Sky" for those of you who didn't realize... This is also the first OST of three. This CD can be purchased at Anime Nation for about $30; its retail price.

As for the quality of the music: I think I'll let these tracks speak for themselves. Trust me, you'll be hooked.
