Tonight performance begins at 8 p.m. at the Hanna Theatre, where the group performs again tomorrow night at 8. At 3 p.m. on Sunday at the Hanna, the band plays an even family-friendlier version of its celebrated holiday concert, featuring a shortened program and its popular interactive instrument “petting zoo.” Tickets to tonight and tomorrow night's concert are $35 to $55. Tickets to Sunday's show are $10. (Niesel)
