Dragon Quest III Symphonic Suite contains the best battle theme and the best ending theme in a series full of great examples of both. Almost all of Dragon Quest's battle themes excel at conveying the menace of some malevolent beast, but the frantic strings and incredibly powerful brass in Dragon Quest III's "Fighting Spirit" add an energy and urgency unmatched in its counterparts. As for the ending theme "Into the Legend", well, there's a reason it serves as the grand finale not only to the soundtrack itself but also to several of the series' best collections. Every second from the unforgettable opening fanfare onward encapsulates the grandeur of an epic fantasy adventure as well as any orchestral ending theme in existence.
Supplementing these two all-time classics are several other standouts. "Prologue" was a new addition to the Super Famicom remake of the game and this London Philharmonic symphonic suite recording, but it's hard to imagine a Dragon Quest III album without the theme's tender woodwinds and oh-so-elegant strings. (The same instrumental combination also works its magic in the subdued yet beautiful "Distant Memories" and "Heavenly Flight".) "Gruelling Fight" is a second new addition to the London Philharmonic symphonic suite, and while it doesn't possess the frantic fury of "Fighting Spirit", a similar sense of urgency is in its simple but powerful call to arms.
Not every series staple in Dragon Quest III manages to stand out. "Around the World" falls short of similar overworld medleys in Dragon Quest IV and V, "Dungeon ~ Tower ~ The Phantom Ship" is functional but forgettable, and while the waltz "Sailing" is pleasant enough, it's hard not to compare it to Dragon Quest V's livelier, more endearing "Bridal Waltz". As these and some of the album's more subtle selections are gathered around the middle of the score, that part of the album might feel a bit slow to listeners unaccustomed to the series' Classical influences, though the highlights from the album more than make up for it.
Note that there are three different orchestral recordings for Dragon Quest III Symphonic Suite - the initial NHK Symphonic Orchestra recording, this London Philharmonic Orchestra one, and later a recording by the Tokyo Metropolitan Symphony Orchestra. The London Philharmonic edition is the best by far, with a virtually flawless performance and a clearer, closer-sounding recording all around.
Dragon Quest regulars and listeners with an appreciation for the score's occasional Classical stylings will be most likely to enjoy Dragon Quest III Symphonic Suite in its entirety. As for series newcomers looking to try out a complete Dragon Quest score, I'd suggest starting with the slightly more consistent Dragon Quest IV first, and from there either continuing on to Dragon Quest III or acquiring its most essential themes via one of the many series best collections available. In one way or another, anyone with a taste for orchestral adventure absolutely must experience some of Dragon Quest III Symphonic Suite.
