man i dont know if any band can match the shitty riffs of coal chamber but i use to be in your shoes so im gonna try to help you out. First off you gotta move on slowly so id suggest to start listening to pantera or black label society something that still has those punch someone in the face riffs but also has solos in dime's case damn good solo's than once you get into the lead guitar check out some melodic death or even a few select non gay metal core bands, than once you get into that is when the fun starts and you get into tech deth and blackened death pretty much anything death metal is what you wanna get to

h but this is just my opinion
