I'm a musician, and I'm down to check out pretty much any kind of show. And I don't just mean varied genres of guitar rock, electronica, or jazz, though I can get into any of these. I've been lucky enough to be exposed to music from lots of different cultures (more on some below), and my ears are open to the whole range of organized sounds.
Having lots of friends in the arts means I like checking out other kinds, whether performances like dance, theater, circus; or galleries, poetry readings, etc. And, like most people, I consider myself pretty smart ;-) so I'll take any opportunity to learn something and discuss about science, technology, or politics from that TED talk or NPR show that so interested you.
When I'm not at work, rehearsal, or practicing/writing or working out, I'm socializing with a fairly varied set of social circles. Some of these are left-wing wackos, anarchists, communists, and various social justice types. Others may sympathize but are more interested in *where the party at*. Both are great: balance is important.
