fwiw, if you're curious, the reason i didn't take instruction in metal guitar is that i didn't enjoy listening to it, partly because i didn't like the culture attached to it. i liked fusion, jazz, prog - stuff that was more intellectual and less macho. metal was something i interpreted as "music for idiots" from a very young age.

and, i started playing at too young an age to benefit from any kind of instruction in punk or grunge - by the time i started listening to it, i could already teach myself that stuff.

my instructional phase was in blues, mostly. hendrix. zeppelin. that pushed into jazz. i was actually playing zappa & crimson with ease by the time i was 15.

then i stopped, because i was having more fun teaching myself soundgarden songs out of guitar world and i wanted to write my own music.
