I want to know the answer to the following question:
Who was well known for important works of traditional blugrass?
All the background I'm provided with is that "Chris Thile of California is a well-known player, and has accomplished many feats of traditional bluegrass, classical, contemporary pop and rock; the band Nickel Creek featured his playing in its blend of traditional and pop styles, and he now plays in his band Punch Brothers.". Is that enough to answer the question?
