Catskill Choral Society — bringing 44 seasons of quality choral masterworks to the region with its spring and holiday concerts — invites singers from around the area to audition for the upcoming 2015 concerts. This coming spring R. Colin Armstrong, DMA, will conduct Franz Joseph Haydn’s Missa in Angustiis, more commonly referred to as the Lord Nelson Mass, and later in the year Marc- Antoine Charpentier’s Messe de Minuit (Midnight Mass) will be performed to mark the beginning of the holidays. Both choral works, written in Classical and Baroque styles respectively, feature soloists and orchestra and promise to inspire and enthrall singers and audience members alike.
