"End of the Century," the movie about the Ramones, is out now, and I've been reading a few of the reviews. I plan to watch the movie, but plans can fall through, etc. But I've learned one thing just by reading the reviews: Dee Dee left the Ramones to become a rapper. (So much for my status as a rock historian.) This was exciting news to me because embracing rap is one of the most important things an advanced artist can do. This shows that at least one member of the Ramones did advance beyond the original, already advanced band.
I also learned from an old CNN.com obituary that Dee Dee "formed a Ramones cover band and became a painter." Both of those things are advanced.
