Ockeghem@600 Concert 11: Missa sine nomine a 5

In light of recent developments with COVID-19 variants, Blue Heron is establishing safety protocols for the protection of everyone attending our concerts this season. We will require masks to be worn by all audience members and volunteers, regardless of vaccination status. If you arrive without a mask, one will be provided to you. We strongly encourage all of our audience to get vaccinated prior to attending and, as a matter of workplace safety, we are requiring all staff, musicians, and volunteers to be fully vaccinated. (Musicians will not be masked during the performance.) We are not currently required to limit occupancy at First Church but we will observe all limits and guidelines set forth by the city or the Commonwealth, and we are offering at least two performances per program to reduce capacity and prepare for any seating adjustments that may be necessary. Additionally, in order to streamline entry to the concert and prevent overcrowding in the foyer, we will sell CDs and other merchandise only at intermission and after the concert. All concert dates, programs and personnel are subject to change without notice.
