What does it all mean?
The Omega Tribe project consists of three main bands:
Sugiyama Kiyotaka & Omega Tribe, which lasted from 1983 to 1986,
1986 Omega Tribe, which lasted from 1986 to 1987,
And Carlos Toshiki & Omega Tribe, which lasted from 1987 to 1991.
Sugiyama Kiyotaka started off with the band as the lead vocals and stayed with the band until 1986, releasing 5 albums in the band's time.
1986 Omega Tribe births the first appearance of Carlos Toshiki in the band. His most notable hit, Kimi wa 1000% was the band's debut single. In the band's time 2 albums were released.
After one of the guitarists leaving the band, and Joey McCoy joining in, the band is renamed to Carlos Toshiki & Omega Tribe. Their biggest hit was アクアマリンのままでいて. In their time 4 albums were released.
An interesting note is that the band continued after 1991, but in a very minor form with no more hits. Sugiyama Kiyotaka and Carlos Toshiki continued in solo careers after leaving the band.
