I just saw Joshua Radin, Schuyler Fisk, and Brett Dennen in concert last night, and it was an incredible show. Besides drunk people who were talking obnoxiously loud during some stuff, the songs were great live and since Schuyler is from Charlottesville she had her mother (Sissy Spacek) sing with her on a few. I got to meet Josh and Schuyler afterwards and got a big hug from Schuyler so that may have clouded my judgment, but only slightly.
If you like folksy acoustic stuff, definitely check it out. Josh and Brett did a cover of Simon & Garfunkel's "Cecilia" which was a lot of fun.
Recommendations: "Winter" and "Star Mile," by Josh, "Hello," and "The Good Stuff" by Schuyler, and Josh & Schuyler's duet of "Paperweight." I'm still working on finding out track names for Brett.
