The line-up for this year's Old Town School Folk & Roots Festival has been announced. Headlining this year's main stage schedule are Los Amigos Invisibles, The Holmes Brothers and The Subdudes. Even if folk and/or roots isn't your thing, the festivities include lots of other activities -- for the dancer in you and the kids you take with you. Old Town staff will even have a stage of their own. The festival runs all day, July 10 and 11, in Lincoln Square's Welles Park.
