Ako personally, Im ok with bands targeting a specific market -- like michael learns to rock doing more ballads than rock, or Hale doing more pop fusion than alternative. Examples ko lang ito. Di kasi natin maialis yung economic factor kung bakit nila piniling maging baduy (sa panlasa ko ha, at sa marami pang iba) kesa magpaka astig sa rock music. Kung andon yung pera eh, wala tayo magawa -- kasi don sila kumikita.
Dream Theatre for example (fave band ko) was hard core prog-rock pioneer, and their first few albums were beast dahil sa hirap ng notations and insane speeds. Non times na yun halos mga rock and metal die hards lang ang nabili ng albums nila, not until they decided to put melodramatic tunes in their following songs, in fact may ballad silang binuo (I walked Beside You) noon -- all just to capture a wider target market.
Metallica also did some transformation as well as Avenged Sevenfold.
Ako kasi nagbabada din ako since HS ako, konting aral sa conservatory but I dropped out of it to work na din. So yung appreciation ko na lang today sa rock music is on the creativity ng bumubuo ng kanta. For one example is Sugar Free -- tremendous talent and song writing, to think na trio lang sila, pero kung papakingan mo ang binuo nilang kanta, iisipin mong 5-man band sila in both instruments and vocalization.
Sino pa ba? Kitchie Nadal's band is one. And Wolfgang ofcourse.
