A guitarist, a violinist, a bassist, a banjoist and a mandolinist walk into the Mondavi Center and start to play. There’s no punchline, only Punch Brothers. The quintet offers a clean and bright acoustic sound for the discerning folk-acoustic-bluegrass-classical listener. As musicians on the rise with their fingers in a number of pies, including lead singer Chris Thile’s hosting of the radio show Live From Here, it should be a delightful evening of music. 1 Shields Avenue, mondaviarts.org.
