Boston Baroque is set to conclude its 50th season with two programs in March and April.

The first program will be a concert of Mozart’s Symphony No. 41 and the Sinfonia concertante featuring soloists violinist Christina Day Martinson and violist Jason Fisher. The concert will be held on March 25 and 26 at GBH’s Calderwood Studio, and NEC’s Jordan Hall.

The second concert will be Gluck’s opera “Iphigénie en Tauride” starring Wendy Bryn Harmer, William Burden, and Jesse Blumberg. Performances will be on April 20, 21, and 23 at at the Calderwood Studio. The 8 p.m. performance on April 21 will be streamed live on IDAGIO, and available to rent on-demand for 30 days following the stream.

The opera will be conducted by Martin Pearlman and will be directed by stage director Mo Zhou, and an outstanding cast. The new production marks the first time Boston Baroque returns to the work in over 20 years—last heard on stage in 1999.
