The Dawn was formed in 1985 and originally consisted of Diaz on guitar,
JB Leonor on drums and Clay Luna on bass. The band's name was derived from a portrait of the
Holy Spirit that symbolized the dawn of a new day (probably found in a book given by the
Sisters of the Holy Spirit to Teddy Diaz, as well as a crucifix which Teddy also received from the same sisterhood), called
The Dawning of the Holy Spirit. Diaz, Leonor and Luna initially wanted a female vocalist but in the course of their search, Jett Pangan auditioned, got the trio's unanimous nod and the quartet started performing in clubs. In 1987, he co-wrote the Dawn's debut single "
Enveloped Ideas", The arrangement of the Filipino traditional folk song, "Magtanim ay 'Di Biro" was also credited to Diaz. Other songs which Diaz wrote or co-wrote were "Dreams" and "The Moon". The band
Introvoys was mentored by Diaz. Before his death, he became friends with
Francis Reyes (who later joined the band as guitarist) where they even spoke of forming a thrash metal side project with drummer
JB Leonor's brother, Dennis. ==Death==
