Meshuggah owns. DEP is pretty damn cool imo, i like em.
Relapse are pretty fucking nifty.
I wouldn't even term DEP noisecore... hmm I can't really think of any hardcore bands that use any truly 'noise' elements.... when you have rhythm or melody in any way, its hard to attach the term 'noise'.
I'm sure many bands have been influenced by noise though.
wait, I thought of a band, Zeni Geva, KK Null is a noise musician and he brings a lot of his weird guitar shit into the band. I suppose TITD and unsane would also then be considered 'noisecore'.
In which case count me in.
I'll give my verdict on the new DEP shortly. I've always liked them and Converge and a few of they older bands of that style (deadguy, canvas, drowningman), but yeah, there is a lot of copycat bands around now.
