Ah, an arrangement of one of the greatest battle themes ever from one of the most underrated and under appreciated RPGs of all time. In Japan, the game was called Romancing SaGa Minstrel's Song, but in the US it was just referred to as Romancing SaGa. It's a PS2 remake of the original Romancing SaGa on the SNES. It's one of my most favorite games of all time.
