Cecilia Bartoli’s album Unreleased, featuring virtuosic concert arias from Mozart, Beethoven, Haydn and Mysliveček, will be released on 19 November 2021. These notoriously demanding pieces were written by the greatest composers of the classical era for the leading sopranos of their day. The music was recorded in 2013 with the Kammerorchester Basel under Muhai Tang and violinist Maxim Vengerov is featured on the Mozart arias L’Amerò Sarò Costante and Ch’io Mi Scordi Di Te? The tracklist for Unreleased was finalized by Cecilia Bartoli during the pause to her performance schedule caused by the pandemic.
