Hironobu Kageyama
The first thing to pop into some minds is: who is Hironobu Kageyama and who cares? What does he have to do with Dragon Ball? While others are left in a haze of wonder, only knowing his deep rich voice. Yes, as you may have guessed, he is the one who sings about two thirds of the original Dragon Ball repertoire. He is the mysterious one who sings the hit Cha-La Head-Cha-La, We Gotta Power, and Bokutachi wa Tenshi Datta (We Were Angels).
Kageyama was born on February 18, 1961 in Osaka, Japan. While still in high school, he and his friends formed the band, "LAZY". From what I can understand they went to perform at "Hello Young" of the Osaka ABC broadcast system and did very well. Soon the members of LAZY were known as "Mitchell" (Hironobu Kageyama - vocal), "Suzy" (Akira Takasaki - guitar), "Funny" (Hiroyuki Tanaka - base guitar), "Pocky" (Inoue Shunji - Keyboard), and "Davy" (Munetaka Higuchi - Drums). But this was only the start of Kageyama's successful singing days.
Unfortunately LAZY didn't last... They had broken up in May 31, 1981, because they couldn't make up their mind on what type of music they wanted to play. (Kageyama wanted to play heavy metal rock.) And thus began Kageyama's solo career. First, he started to sing songs for anime TV shows (Columbia Record) rather than original work. And hell was he successful!
In 1989, Hironobu Kageyama was chosen to sing the famous Cha-La Head-Cha-La. He dominated the Dragon Ball Z Hit Collection CD II! The only track that was not sung by him was Detekoi Tobikiri Zenkai Powaa (Bring Out That Full Force Power) performed by Manna. By this time he had been raised to the title of the best anime singer. He stayed working with Dragon Ball Z until 1998. Then he said good bye with the 1998 Dragon Ball Live Concert. Although even 'till this day he still sings the songs and makes new versions of them as well, such as the CHA-LA HEAD-CHA-LA (2005 ver.).
Even though he did perform mainly for Dragon Ball, he also sang for other animes as well. In the most recent years he has teamed with Endo Masaaki and toured around Japan reliving some of the old songs from LAZY, anime, singles, and past albums. But all the songs were re-arranged for two acoustic guitars.
From what I hear he is now married with two daughters. He likes baseball, skiing, and messing around on the computer. He sang a song called "Baseball Tengoku" (Baseball Heaven) for a baseball radio show. And currently he has his own official Web site (see links). He is also apart of "JAM Project" (Japan Animationsong Makers Project). From 1977 to now he's always improving, not only in performance, but in his stature for 27 years, as well.
