According to the Dutch newspaper Het Parool, Armando Cairo has a repertoire of fine compositions (his own and those of his band members), and a rhythm-section any soloist would envy him. Next to his own, his repertoire also contains jazz-compositions by Archie Shepp, Clifford Jordan, Thelonious Monk, Bennie Wallace, Roland Kirk, Sonny Clark, Nicolas Payton and Billy Strayhorn.

In 1996 the CD Redheaded Sirens appeared.
In 1999 the quartet released Tenor Brutality!
