Pittsburgh legend Joe Negri and his quartet provide the accompaniment for his moving jazz treatment of the liturgical Mass. Featuring soloists Maureen Budway (mezzo soprano) and Thomas Douglas (baritone). Paul Basler’s interpretation of the Mass provides a suitable pairing, including African overtones. Also on this program is the Missa Kenya of Paul Balser. Together, they make a beautiful closing to Bach Choir’s concert season.
