We've got three pairs of tickets to see Smog's Bill Callahan play this Saturday at the Museum of Fine Arts. Showtime is 7:30. Here's the catch: you must be able to come pick tix up in person, during business hours (8:30 am - 5:30 pm), between now and Friday. Hit us in the comments section with an email we can reach you at pronto. First-come, first-served.
