Well, we do have The Official Heavy Metal Topic, but as you noted, BZP isn't really active so I doubt it matters lol.
Recently, I've been listening to a lot of Carcass, Cattle Decap, Fallujah, and Allegaeon. Been on a bit of a death metal kick lol.
Favorite albums (in no particular order) would have to be Demanufacture by Fear Factory, The Impossibility of Reason by Chimaira, Rust in Peace and Peace Sells by Megadeth, Dirt by Alice in Chains, Hatebreeder by Children of Bodom, and Blood Mountain by Mastodon.
But anyways, don't expect this topic to be too active.
