One mezzo-soprano, Cecilia Bartoli, pays tribute to another -- 19th-century diva Maria Malibran -- in this live concert from Palau de la Música Catalana in Barcelona, Spain, celebrating Malibran's 200th birthday. In addition to performing favorites from Bartoli's "Maria" album (including Felix Mendelssohn's "Infelice"), she lends her voice to selections not available elsewhere, such as an exquisite rendition of Gioacchino Rossini's "Willow Song."
