One of the immortal composers of classical music, Peter Ilyich Tchaikovsky, will join the ranks of such LGBT icons as Alan Turing and Sylvia Rivera with a biographical memorial in Chicago’s award-winning outdoor LGBT History Museum “The Legacy Walk.” Sponsored by Ravinia Festival, Ravinia Board Chairman Jennifer Steans, Illinois State Senator Heather Steans (7th District Democrat), and Ravinia President and CEO Welz Kauffman and husband Jon Teeuwissen, the Tchaikovsky exhibit will be unveiled at 2 p.m. Saturday, Oct. 13, on the Legacy Walk, which spans 3245–3705 Halsted St., Chicago. Award-winning jazz pianist-composer-accordionist Ben Rosenblum will give a street performance at the dedication and will make his Ravinia debut later that night. A “Dedication Celebration” will follow the installation at Sidetrack, 3349 N. Halsted St., Chicago.
