They just added some dates:
http://www.thefelicebrothers.com/tour.phpThey are swinging through the South and Southeast in Feb, and the Northeast in March and April.
Excellent live band, go see them if you get the chance. 14 to 20 bucks for a band of this caliber is a steal!

Be advised that in Feb they are the opening act, while in March and April they are the main act.
Personally, I would not make a great effort to see them for the 35 minutes or so they would get as openers...unless of course, you like the main act. While I think The Old Crow Medicine Show are a fun and tight band, I would not be surprised at all if many folks prefer the energy and talent of the Felice boys.
