Wanna go see Mason Jennings on Saturday??
Mason only has one concert scheduled, and it is at First Avenue on Saturday night. This concert is sold out, but the HellHouse has one extra ticket! With the TicketBastard fees, the ticket is still a bargain at $19! The show is at 6pm so you won't even have to stay out until all hours if you don't want to. If you've never heard Mason's stuff you are missing out! Here's his web page: http://www.masonjennings.com/
iTunes has his music. So does eMusic.com if you don't want to deal with the Apple protected format.
As I said, there is only one ticket. First come, first serve. Unless of course you want to offer more money than the first person. I'm perfectly willing to let y'all get into a bidding war over it.
