The annual Chamber Music concerts season starts tonight at 8:30 pm at the Salón de Actos of the Patronato de la Ciudad Colonial, Calle Isabel la Católica (in front of Columbus Park). The concerts were usually held at the Capilla de los Remedios but this year, the 12 concerts, scheduled for the last Thursday of each month, will take place at the headquarters of the Colonial City board. Performing this evening is the Camara Ars Nova Orchestra, conducted by Francois Bahuaud; soprano Ivonne Haza; and National Symphony Orchestra clarinet player, Jorge de Jesús Torres.
