I'm a huge fan of Dave Matthews, and possibly an even bigger fan of his "solo" concerts with Tim Reynolds. I've seen them twice live, and of course have the Live at Luther College CD as well as several recordings from shows they have given.
But woe is me. I saw an announcement that they were going to play at Radio City Music Hall on April 22 and decided it was too expensive to go down there for a show; but I missed the announcement that they will be playing at Amherst College, MA on April 21 (and the tickets are all sold out now. :( )
