Music is a universal language insofar as you don't need to know anything else about a musician that you are playing with other than that they can play music. It doesn't matter what their music is, you can find something that you can play together, with what their culture is. The dialect part of it comes into play, but nothing like the differentiation that language sets up, for example.
Jerry GarciaThe real problems are cultural. The problems of the people who take drugs as a cultural trap - I think there's a real problem there, the crack stuff, the hopelessness of the junkie. The urban angst.
