Renowned jazz musicians John Pizzarelli and Jessica Molaskey will record their syndicated American-songbook radio program, “Radio Deluxe,” live at the Mahaiwe. This popular show mixes and matches songs in medleys and sequences that flow like a continuing dialogue about life, relationships, and popular culture itself. The common denominator is a playful sense of humor. The husband-and-wife hosts are masters of off-the-cuff repartee. Special guest TBA.
