Lonny Price will direct the Aug. 13-15 concerts, which will boast LuPone as the sharp-shootin' Annie Oakley and Mitchell as Frank Butler. The artists will be backed by the Chicago Symphony Orchestra, which will be conducted by Paul Gemignani. Additional casting will be announced at a later time.

LuPone's last musical theatre outing at Ravinia was Rose in Gypsy, a role she later repeated on Broadway to Tony-winnning effect. LuPone previously played the role of Oakley in a one-night-only benefit concert at Lincoln Center Theater's Vivian Beaumont. The upcoming concerts will celebrate the 150th birthday of Annie Oakley.

The Ravinia Festival 2010 will also feature a Sondheim Gala celebrating the 80th birthday of composer Stephen Sondheim. Directed by Lonny Price, the July 31 benefit evening will boast the talents of Tony Award winners LuPone, Audra McDonald, George Hearn and Michael Cerveris, who have all been featured in Ravinia's Sondheim celebrations since they began in 2001. The concert will feature songs from such Sondheim musicals as Sweeney Todd, A Little Night Music, Passion, Sunday in the Park with George, Anyone Can Whistle, West Side Story and Gypsy. Paul Gemignani will conduct the Chicago Symphony Orchestra.

Three-time Tony nominee Kelli O'Hara will return to the Ravinia Aug. 4 for a solo concert in the Martin Theatre. Also on the Ravinia bill: Nathan Gunn in The Marriage of Figaro (Aug. 6 and 8), Hershey Felder in Maestro (Sept. 7) and a presentation of Leonard Bernstein's Candide Vocal Suite (July 23).
