The Wellfleet Cultural Council and the Wellfleet Library will Sponsor a concert at the Wellfleet Library on Friday, June 21st at 7:30 PM. The concert will include two compositions by part-time Wellfleet resident Grammy Nominee composer Hayg Boyadjian, who may be familiar to some Wellfleet residents having had works performed in the past at the library. Two outstanding virtuoso musicians will perform: Constantine Finehouse-piano, from the New England Conservatory Faculty, and Mickey Katz-violoncellist, member of the Boston Symphony Orchestra, who also performs frequently in chamber music ensembles. Pianist Finehouse will perform Boyadjian’s solo piano piece “Kaleidoscope”, and the two musicians will perform Boyadjian’s “Third Canticle” for cello and piano. Also on the program will be Beethoven’s well known Sonata No. 3 in A major for cello and piano, and Claude Debussy’s Sonata also for cello and piano.
