Ravinia’s large-scale presentations of Stephen Sondheim’s works have been critically acclaimed audience-pleasers. But there is more than one way to approach an artist of Sondheim’s magnitude. Pianist Anthony DeMare brings a fresh approach to his Aug. 25 concert, Liaisons, for which he commissioned several of today’s influential composers to reimagine some of Sondheim’s brightest songs as piano pieces. Works will include The Demon Barber by Kenji Bunch, Being Alive by Gabriel Kahane, Color and Light by Nico Muhly, I’m Excited. No You’re Not. by Jake Heggie, Send in the Clowns by Ethan Iverson and many more. Reserved seats are only $10.
