Fire Bomber, (like Sharon Apple from Macross Plus) are a number of singers and musicians! They are made up of Nobutoshi Hayashi who voices Basara, Yoshiki Fukuyama who usually sings for Basara, Tomo Sakurai (voice of Mylene) and Chie Kajiura who both sing Mylene. When a song is by Fire Bomber together it is most likely to be sung by Chie Kajiura and Yoshiki Fukuyama. They have all performed together as "Fire Bomber" at:

"Lets Fire" Fire Bomber 1st Live at Nippon Seinenkan
"Lets Fire Again" Fire Bomber 2nd Live in Nakano Sunplaza

The CD "Live Fire" is recorded from the first concert. The musicians are mostly from a band called Humming Bird (not to be confused with the anime and real singers Humming BirdS! ^_^;;). Fukuyama is one of the two vocalists for Humming Bird, who had a set of gigs at "Eggman" in 1996.
See the Humming Bird section for more information.

Fukuyama also sang Fire Bomber songs at Macross Onenight Stand - the 15th Anniversary concert.
