Four Friday-evening concerts-one each in November, January, February, and April-are designated "Casual Fridays" this season. You are invited to wear your favorite casual attire, and to arrive early to enjoy a free, pre-concert reception before you take your seat. This lower-priced series also features a special section for Conductor Cam seating, which allows patrons to watch the conductor from the orchestra's perspective. Then, immediately after the performance, head to the post-concert reception, where, besides enjoying live music, snacks, and a cash bar, you are invited to mingle and share what you've just experienced at the BSO concert. Also featured pre-concert is a mini-instrument playground. Come try out a variety of orchestral instruments with the help of BSO volunteers.
