Combining modern dance technique, Haitian folkloric dance, and live percussion, Jean Appolon Expressions’ full length production of Angaje will be held at Seven Hills Park in Somerville this Saturday (June 13) as part of the Somerville Arts Council’s third annual Dancing in the Streets Festival. The performance, set the music of Haitian musical icon Toto Bissainthe and directed by founder Jean Appolon, is inspired by the struggle against homophobia and the power of Haitian folkloric culture in the fight for justice. The performance begins at 8:30 p.m. and is free. More information on the Jean Appolon Expressions organization is here.
