As an annual partnership between Cleveland Metropolitan School District and Great Lakes Theater, teachers, theater professionals and Cleveland students, the All-City Musical brings together a wide array of talent. Now in its 15th year, the collaboration presents Rent, the musical that has permeated every ounce of American culture. Its beloved story, message of living in the moment and shabby-chic bohemian aesthetic make for a touching and important look into the artistic lifestyle. The musical is only showing this weekend in the Ohio Theatre. Performances take place at 7:30 tonight and tomorrow night and at 3 p.m. on Sunday. Tickets are $15. (Stoops)
