I don't feel the need since I don't dig the style. I mean, if people link me to some good stuff, I'll give it a chance, but I've listened to enough terrible bullshit under the "prog metal" moniker that I've grown jaded of the search.
There are a small, small fraction of bands that do it well (and no, I'm not saying BTBAM is inherently among them, I admitted they were a guilty pleasure), but for the most part, 99% of prog metal is haphazardly thrown-together contrasting sections, masturbatory riffs, featuring whiny, wailing vocalists.
Its almost as if the majority of metal musicians don't understand what "progressive" actually means as a musical quality (a song that actually progresses and builds up in a sophisticated yet logical fashion). I'd liken a lot of post-metal to be more akin to true progressive metal than what is passed off as such today.
