Today from noon to 5 p.m., Severance Hall hosts a free day of music and community engagement. The Cleveland Orchestra Youth Orchestra and Cleveland Orchestra Youth Chorus will perform, and there will be a special presentation of Dr. Mark Lomax II's 400: An African Epic, a "journey through music that chronologically represents the Afrikan experience, past, present and future." A discussion led by Joy Bostic, interim VP of the Office of Inclusion, Diversity and Equal Opportunity at CWRU, will follow the performance. There will also be line dancing in the Bogomolny-Kozerefski Grand Foyer. Admission is free, and tickets aren't required. (Niesel)
