A definite must!
Motoi Sakuraba was an instant favourite of mine when I first heard his work on Star Ocean, and I believe that Valkyrie Profile: Lenneth is the pinnacle of his work. Strong techno-rock, amazing calm pieces and there's not much more to say other than this album is definitely strongly recommended for any music collection!

Remastered renamed ost
This is just the remastered version with the tag lenneth slapped on for the re release of the game on the psp, the sound quality is great and the packaging is pretty cool too.

This is considered some of his best work and considering how hard the original prints of VP1 ST's are I would advise getting these before they go oop also.
