Following their presentation of selections from Rhiannon Giddens and Michael Abels’ opera “Omar” at the Prior in spring 2023, the Boston Lyric Opera returns with a newly commissioned work. The song cycle “The Wanderer’s Tethering” combines poetry by Boston Poet Laureate Porsha Olayiwola and music by Boston-based composer, vocalist, and multimedia artist Mason Bynes. It follows the story of Tobi, a descendant of the Igbo community whose members were stolen from modern-day Nigeria and led a revolt on the shores of Georgia in 1803. Bynes’ music merges Negro spirituals and Igbo folkloric music, reflecting the transformation experienced by the contemporary protagonist as she claims her own identity. The program will also include stirring selections of chamber music by Castle of Our Skins.
