One of the main draws of the Avett Brothers for most people is their songwriting. And, as much as we may bash on Rick Rubin, he does seem to have a respect for their song writing (there are several very unorthadox songs on I and Love and You that he certainly let slide.) I think that even if the Avett Brothers become giant sell outs and start fine tuning their music for the masses, they'll still be writing their own music. And they'd probably be writing some of the best mainstream, commercial music we've heard in a long time. I just hope that it doesn't come to that, and that they can stay in touch with their indie roots, as many other indie artists who have struck it big have managed to do.
