You guys ARE forgetting about one guy who really revolutionized the music scene but i am not saying to give him all the credit.
That guy is RICO BLANCO. Compared to Ely, Rico writes their songs (but not all) and this guy is a great innovator when performing onstage, imagine hearing a whole new version of their songs in their respective albums.
Another great innovator is Ricci Guranggo (tama ba?) Imagine, 2 na ang sumikat na kasama sya (not pinasikat nya): Barbie Almalbies and Kitchie Nadal, I won't wonder if Lou Gee will follow the same path as those two. Magaling kasi ang diskarte nila sa live performance.
Another is Barbie Almalbis. Imagine christian songs going into mainstream, that is freakin' hard man.
Also with all due respects to those who contributed to the philippine rock scene.
Juan dela Cruz - who i think started it all. Sensya na, di pa ako existing nung era nila eh.
The Dawn - Hands down, one of the greatest influences.
True Faith - Another great live performer
Side A - i think naging foundation ng mga showbands today
Wolfgang - bringing the R into ROCK
Razorback - hebigat sounds man
Slapshock - okay, okay let's give them a little credit for going mainstream to give light to their genre with Greyhoundz et all. Aminin man natin na mas magaling ibang hard core kesa sa kanila, it's their songs we sing to when we hear it on the radio.
Bamboo - for bringing back the patriotism of filipinos during the dark times (Noypi & Hallelujah)
Urbandub - Grabe, a whole new kind of music from Cebu.
Kung meron pa ako nakalimutan... pakidagdag na lang. I hope na di ako nagkamali sa pagsabi ng sarili nilang influences in the music industry, well these are my opinions anyway...
