Luker (The Music Man, Show Boat) and Mazzie (Carrie, Ragtime) will be joined by Gretchen Parlato, Sachal Vasandani and Tia Fuller in The Bridge to Broadway July 2 at 7 PM in Rockefeller Park.

Here's how the event is described: "Broadway repertoire crosses with jazz and pop in this original concert production exclusive to the River To River Festival. Jazz greats, vocalists Gretchen Parlato, Sachal Vasandani, with saxophonist Tia Fuller, take on classic Broadway show tunes, along with multiple Tony nominees Rebecca Luker and Marin Mazzie, performing songs from outside of the Broadway canon."

Theatrical offerings at the festival include a staged reading of Anton Chekov's Three Sisters, directed by Maureen Towey and featuring a cast of actors all over the age of 65, June 22 at 1:30 PM at Good Companions Senior Center; William Shakespeare's Twelfth Night, presented by the New York Classical Theatre at the Castle Clinton, June 26-July 15; and Samuel Beckett's Act Without Words II, presented by Company SJ at Theatre Alley, June 26-29.

Philip Glass Ensemble: A Retrospective will also take place during the festival. The concert, celebrating Glass' 75th birthday, will be held June 20 at 7 PM in Rockefeller Park.
