I wouldn't say I "grew out of it." I mean, I don't listen to JUST metal any more. I go through phases. For a period of about a year I mostly just listened to IDM, post-rock, and a bit of jazz. The only metal I really listened to often was Buckethead.
Oh, for you geezers out there, "IDM" means "techno that is pleasant to listen to while sitting around your house, rather than most techno, which is only pleasant if you're a dancing e-tard.
NOTE TO THE MODS: "E-tard" is not meant to be a cheap bypass of the wordfilter. It's a term for people who do too much ecstasy. Just thought I'd point that out if you guys were feeling trigger-happy today.
I finally learned something new. I'm a geezer.
