If you've been avoiding the Mag Mile  since Thanksgiving, Sunday might be a good day to give in. For the second year in a row, famed cellist and CSO creative consultant Yo-Yo Ma will play a pop-up performance at the Shops at North Bridge (520 N. Michigan) Sunday afternoon. Following a performance of Bach's Brandenburg concertos (No. 1-6) by members of the Civic Orchestra (the CSO's training ensemble), Ma will join the Civic brass for an aria from Handel's Rinaldo arranged by trumpeter Matt Barker. The show runs from 2 p.m. to 5 p.m., and Ma will appear for the aria at 4:15 p.m.

Additionally the ensemble will play from 1 p.m. to 3:35 p.m. at the Christkindlmarket (50 W. Washington). Both performances are free—your first gift of the season.

Go: Yo-Yo Ma and the Civic Orchestra perform Sunday, December 7 from 1 p.m. to 3:35 p.m. at the Christkindlmarket (50 W. Washington) and from 2 p.m. to 5 p.m. at the Shops at North Bridge (520 N. Michigan). Free.
