I've found that when i look at a bands entire career, some of their best music usually is in their first couple albums. Its when they are raw and coming out with a unique sound. Look at bands like Korn and Deftones and so many more. They have a DGAF attitude and its raw and crude and much more in your face.
Conversely, something I love trying to do is find raw outtake songs by other well known bands. Led Zeppelin is really cool to do this too. They laid down so many versions of songs before refining things and getting the final version. Those are some of the most raw versions of famous songs and show the brilliance they had. It just gives new perspective to familiar sounds.
