little of column A, little of column B
I'd say my taste is more for the old timey pickin but some of it can get a bit hokey, the vocals in particular. Some of the new stuff can be a bit redundant though, the String Cheese Incident comes to mind, some of it just keeps draggin on and on and it starts hurtin from a lack of substance.
Have you heard David Grisman's stuff? I'd say what I love the most is new artists (well the dude is old but he's no bill monroe) who take the old tyme sound and put their own spin on it.
A group you may want to check out is the creaking tree string quartet, they're outa Toronto so I'm not sure how well known they are down south. They do the newgrass thing with a bit of jazz/flamenco thrown in but a real tight and original sound.
Feel free to throw out some obscure names, I'm always lookin to find new stuff and I'm definatly no expert on the genre.
