rick rubin style minimalism has been done already... it's retro, retread, rehash at this point (neptunes, cool kids, etc.). that's not punk, it's tribute. the only problem w/ grime being hip-hop's answer to punk is that it never truly crossed over to our side of the pond like punk rock did very quickly after it began (well, you took from our rock music, but i digress). no, the truth is that hip-hop itself paralleled punk from the start. aesthetically speaking, it's punk in its purest form.
