Rosario "La Tremendita" Guerrero and her Iranian peer Mohammad Motamedi team up for Qasida, a musical endeavor that "explores the roots of flamenco in the richly varied poetic songs and improvisations" provided by Motamedi, a rising star in the Iranian classical world. Billed as "flamenco meets Persian classical music," the concert begins at 7:30 tonight at the Cleveland Museum of Art. Tickets are $53 to $69, $48 to $62 for museum members. (Niesel)
