Please recommened some Metal bands?

Hmm, good power metal band is Holy mother. Hard to find, but their newest album, Criminal Afterlife rulez...
Good deatmetal band is Soliwork (but IMO Natural born Chaos (or something like that) isn't good... I more like The Chaiheart machine)
Good death metal band is also Fear Factory, check out their best album - Demanufacture. Vader is also good.
And black metal - Borknagar!!!!!!
 
These bands are probably more progressive metal...

Opeth
Dream Theatre
Liquid Tension Experement
Enchant
Meshuggah
Cog (if you happen to live in Australia ... this band has a few high quality EP's out)
