I am looking for new challenges, im really stuck here. I want look on some death metal riffs, do anyone know of any lessons, videoes, tabs, whatever. That can give me an insight of death metal techniques? I know palm muting, alternate picking, sweep picking. But is more into some rhythms or whatever.

Thanks in advance!
