Tango del Rey will host an unusual concert on Friday, Jan. 13, featuring tenor Ivailo Giurov and soprano Aurica Avonaires. Giurov was mentored by the great Luciano Pavarotti for three months in Italy in 2005 and Avonaires is a well-known singer in Bulgaria and a centerpiece of several Moscow orchestras, including Bolshoi Theatre’s “Kapriz.” The two will unite for a duet to perform some of the most beautiful and timeless arias of the classical world. Guirov performed at the San Diego Civic Theater in 2007 and 2008 as the lead soloist in the role of Camille de Rossillon in the “Merry Widow.” With the same role Giurov gave more than 80 performances in more than 20 other opera houses in the U.S. and spectacles in every major Japanese opera hall. Avonaires is a young opera actress who has been a singer at the Moscow Mayakovsky Theater and various orchestras like The Concert Brass Band, Moscow Folk Orchestra and Moscow Youth Chamber Orchestra. She participates as a singer in Moscow’s dramatic theaters, where she performs solo arias by Weber, Verdi, Bellini, Tchaikovsky and others. Tickets vary, but range from as low as $20 per adult per act to $25 for the entire show. Children 10 to 21 are $10 or $11 per act and free for those 10 and younger.
