G.U. GAME MUSIC O.S.T.

.hack//G.U. GAME MUSIC O.S.T. is the first of the two .hack//G.U. Game OSTs. Composed and arranged by Chikayo Fukuda of the original .hack games' soundtracks, the soundtrack follows a similar style to the original games. This can be seen in returning vocalist Tomoyo Mitani, who performs in several songs on this O.S.T., including the series theme song "Yasashii Ryoute". Both Japanese and English versions of the song are used in the series. She is sometimes accompanied by the male tenor Yasutaka Anzai. The soundtrack features a majority of the tracks featured in Vol.1 of .hack//G.U. and, unlike the original game soundtrack, is not a soundtrack for all four games. There are three discs included: a background music CD, a drama CD, and a bonus CD.

Similar in approach to the original game soundtrack, the first CD consists mostly of music during active gameplay. The second disc is a drama CD, consisting of music featured during cutscenes. The third disc includes a desktop theme song to replicate the .hack experience on a computer, and two trailers from the Tokyo Game Show, plus various sound effects.

Disc Three
Disc 3 contains the first episode of Online Jack, the Tokyo Game Show Trailer, the Tokyo Anime Fair Trailer and a Desktop and Sound Theme for your personal PC. Disc 3 is/was only availale in a Limited Edition set. Currently out of print/NLA. Discs 1 and 2 still available as a set.

Tasogare no Horousha/Vagrant of the Twilight
Note: While there isn't a song present in either the soundtrack or the game with this title, these lyrics are printed in the booklet and its vocals credited to Tomoyo Mitani and Yasutaka Anzai. This is a Japanese translation of some of the songs that have their choruses in a language unique to the game.

Hulle Granz Cathedral
Notes:
 * The words to the Hulle Granz Cathedral song are extremely similar to the lines from the Epitaph of Twilight, seen in the very beginning of .hack//INFECTION and read by Aina in Δ Hidden Forbidden Holy Ground.
 * According to the Epitaph of Twilight, the songs "Aura's Theme"/"The Hope of Dawn" and "Hidden Forbidden Holy Ground" are the sequel to Hulle Grantz Cathedral.
