To me, he embodies The classical guitarist with all the clichés attached. But he can also make any material his own, or use forms with humor. He's got good compositions too.
There are several ways to roam the world. But if you want to do it like a king, you have to master this. Maybe mix it with that. Or this (spanish spoken here). Then, you can bring your old acoustic guitar, hit the street and sing.
This might lead you to learn to play guitar, to write poems, to sing, or just to watch and listen more intently. Kelly joe Phelps, from washington state, is one of the most beautiful musicians I've ever seen. He's got a great way to play traditionals and his originals are mesmerizing.
He wasn't the greatest technician on earth (he only studied a short time with a teacher, as states his biography), he wasn't really famous outside Brazil, in spite of the many recordings available under his name, of his various talents (drawing, designing a new string instrument), but his playing is really endearing, and whatever the material, originals, bach or chico buarque, he made his point across easily.
