Dude, I’m not a rap fan, but you can’t deny the uniqueness, creativity, and influence of RATM The work they did with bass wah’s, guitar pedals, and blending hard rock with a rapper vocalist puts them up there. Tom Morello revolutionized the guitar. When people list the greatest guitarists of all time, it’s a bunch of classic rock guys that all follow blues scales and what not. But then they throw morello on there too. To turn the guitar into something that could imitate a synthesizer, and then create a sound that influenced every other band that fused rap with rock from then on earns them a spot. Plus they were influential with their activism, being one of the most notorious protest bands of all time.
