I have a fairly eclectic taste in music, and it shows when I think about my five favorite artists. Four of those are Rush, Red Hot Chili Peppers, The Beatles and (the most recent addition) Kanye West. All revered throughout their community of contemporaries and listeners, all well-known to the general public.
The fifth artist? Between the Buried and Me. Never heard of them? Not surprising, seeing as their genre is progressive death metal.
