Well, most straight-up death metal is going to contain things like that... Nile Dim-Mak, and Decapitated come to mind as "clean" death metal bands, with my personal favorite being the latter. For not so clean... Origin, Cryptopsy, Vehemence, Bloodbath...
Thanks for the support Elysian Blaze, and yes I enjoy bands that are Melodic Death Metal, some that cross over to black such as:
A CANOROUS QUINTET, WITHOUT GRIEF, EMBRRACED, DISBELEIF, MUTANT, THEORY IN PRACTICE, GOREFEST, BLOODBATH, ENTOMBED, EDGE OF SANITY, ILL DISPOSED and SYMBYOSIS
Nice to see we still have Pierced From Within supporters around!
