Hamid Al-Saadi, Iraq's foremost purveyor of the maqam tradition, is renowned for his powerful voice and highly ornamented style, as well as his comprehensive knowledge of the intricate details of the music and poetry of Iraq. He teams up with Safaafir, the only U.S.-based ensemble dedicated to performing the Iraqi maqam in its traditional format, for tonight's special concert at the Cleveland Art Museum. Al-Saadi performs very rarely and is considered a master. The concert begins at 7:30 p.m., and tickets cost $33 to $45, or $30 to $40 for CMA members. (Niesel)
