Only a hand full of bands can really ever pull of what i like to the call the long effect. its not something any amount of scales or music schools can teach you.sitting in your room playing chromatics with a metronome makes no difference.
the long effect is the sum of a song. its the fist pumping spirit that very few bands can achieve. you cant find it in a 3 minute pop song. its the musicial journey through a song that "is greater than the sum of its parts." look at to bid you farewell by opeth...thats the long effect. the whole song is a roller coaster of parts. its goes from acoustic to full out distortion, and everything in between. by the last acoustic verse, your riding the high of the entire song.
or look at voice of sanity by gizmachi. after the 8 minutes of maddness, the min.6-min.7-root lick with cln vocals captures the whole mood of the song.
many bands try to reach this long effect,although they dont really get it.
bullet for my valentine/A7X,and other punk/metal bands (IMO) have a sound that almost reaches this effect. they sort of reach the melodic sense of the long effect, but you can never really get it when u have a mainstream sound. they only scratch the surface of a really good song..most people enjoy this surface music, but it will never be able to match the underground sound. the song has to travel..its got to portray more than 1 sterile emotion.
