I first heard the soundtrack about 7 years ago. It was composed by Manabu Namiki, who does much of the music for Cave shooters. In 2009, an arrange album for Dai-Ou-Jou was published by Cave featuring a variety of top artists in the game music world. The music is transcendent; it exceeds any possible auditory desire I could ever have. I have to pick this as the best arrange album released in 2009. I made some scans of it.
The next two scans are of the obi, which means "belt" in Japanese. However, it is more colloquial to say "spine card". The obi, or spine card, covers the spine of the jewel case and displays pertinent information about the CD, such as the catalog number, release date, title, bar code, etc. Almost all Japanese CDs contain an obi, and they are collectable items. People tend to pay less or not pay at all for CDs that are missing the obi. Rarely do obi have any sort of interesting artwork. But this one does.
The line-up of arrangers on this CD is impressive.
The first track was arranged by Yasuhiko Fukuda, who composed Emerald Dragon for the PC Engine, which I have listened to many times.
The second track was arranged by Yasuhisa Watanabe, a member of Zuntata, well known for Metal Black. His nickname is "Yack". I am very familiar with the works of this composer.
The third track was arranged by Kohta Takahashi, whom I am not very familiar with. He has done some work for Namco series, such as Ridge Racer and Tekken.
The fourth track was arranged by Ryu Umemoto, whom I am not very familiar with.
The fifth track was arranged by Motoaki Furukawa, whom I am extremely familiar with. I've been listening to his music for nearly a decade. He is foremost a talented guitarist and has composed music for several early Konami games, such as SD Snatcher and Xexex.
The sixth track was arranged by Yuji Takenouchi, who also composed music for several old Konami games. He composed the music for the sequel to Metal Gear, as well as Space Manbow.
The seventh track was arranged by Kinuyo Yamashita. She also worked for Konami and composed the music for Castlevania, the very first one. The reason why I bought this CD without even wondering if it would be good is because of Yamashita's involvement. If the composer for Castlevania makes something, then you listen.
The eighth track was arranged by Hiroki Kikuta, an old Squaresoft composer, well known for Secret of Mana, and its sequel Seiken Densetsu 3.
The ninth track was arranged by Motoi Sakuraba, who probably has the largest discography in all of video game music. I am very familiar with his music, but I can't say I've even listened to half of what he's composed. Most notably, he's the man behind the Star Ocean and Valkyrie Profile series.
The tenth track was arranged by Kota Hoshino, whom I am not very familiar with. I know he's done a lot of work on the Armored Core series, though.
The eleventh track was arranged by Akari Kaida, whom I am somewhat familiar with. Most notably, I can recall her work on Breath of Fire III. She's done music for several other Capcom games as well.
The twelfth track was arranged by Tomoko Sasaki, who composed the music for Nights, a popular Sega Saturn game.
Oh, and I can't forget the guy that originally composed this music, Manabu Namiki:
