Classical music has long been popularly regarded as a staid — nay, perhaps even boring — genre. The 2016 documentary film What Would Beethoven Do? attempts to challenge that perception and reveal the rise — and revolutionary nature — of the music. The movie focuses on renegade composers and innovative musicians as they explore questions like why we create art and why we should care about art — not just as individuals, but as a society. Presented by the Chagrin Documentary Film Fest, the movie screens tonight at 7 p.m. at the Orange branch of the Cuyahoga County Public Library. It's free, but registration is requested on the library website.(Adrian Leuthauser)
