Sounds like the ad just wanted to catch people's attention with an easily identifiable name rather than anything else... Ramones vs. Death, apples and oranges if you ask me. They sound completely different. Death ended up sounding more like 70s RAWK with a funk tone (like the bulk of 70s rock). They should have compared them to MC5 rather than The Ramones' powerpop sound.
Modern music doesn't have a color or a racial claim that goes with it. It evolves into what it is by different influences that actual written history can't always account for. Ex. Scott Joplin was the son of a slave and freeborn taught by a German music professor (teaching in the U.S.) because he had the passion for music and wanted to learn. He's the said godfather of ragtime/dixieland... and so forth into jazz. At least that's the story we get. In the 20s, EVERYONE is playing jazz and changing it about, everyone contributes. Rockabilly came about via the combination of blues & country blah, blah.. everyone has a place in the history of modern sounds....
I haven't even seen the documentary yet, but always a fan of Death. I keep meaning to see it. Glad to get some reviews here.
