You might argue that it's a thread that's done to death, but I guess what people would recommend keeps changing anyway.
Having been on a massive metal hiatus since my late teens I've recently got back into metal in a huge way and am looking for new bands. Recently I have been mostly loving (not in order of preference):
Opeth (obviously)
Meshuggah
Dream Theater
Devin Townsend Band
Strapping Young lad
Slayer
Tool
The Haunted
NuMetal (the era I completely skipped) still leaves me completely cold as do wanky emo-ey bands singing about being bullied in stereotypical song structures.
I like many musical genres, as many others on this board also seem to, but what other metal would you suggest, given the above?
