Liaisons is a landmark commissioning and concert project, conceived by acclaimed concert pianist Anthony de Mare, based on the songs of legendary musical theater composer Stephen Sondheim. The project has brought together 36 of the world’s foremost contemporary composers to "re-imagine" one of Sondheim’s songs as a solo piano piece.

The result is a brand new world-class piano repertory that reveals Sondheim’s influence across multiple genres and generations, with a roster spanning the classical, jazz, opera, pop, musical theater and film worlds, Composers range in age from 30 to 75, representing seven countries and 29 Grammy, Pulitzer, Tony, Academy and Emmy Awards. Both an homage and a celebration, Liaisons makes the case for Sondheim as one of the 20th century's most influential composers - as at home in the concert hall as on the Broadway stage.

Pianist Anthony de Mare, known as a champion of contemporary classical music, has also been credited with the reinvention of concert theater. For Liaisons, individual pieces can be combined to form an infinite variety of concert, recital and residency programs; venues can work with de Mare directly on shaping the program best suited to their audience, from recital series to jazz festivals.

Sold-out houses and rave reviews have greeted Liaisons concerts across the country at Ravinia, The Mondavi Center, the Cliburn Concert Series and Gilmore International Keyboard Festival among others. The collection received its NYC premiere over a series of three concerts at Symphony Space from 2012 – 2015, described by Anthony Tommasini of the New York Times as "not just inventive piano arrangements but new compositions requiring formidable virtuosity.”  In 2016, he premiered the project with tours in both Australia and the U.K.

In celebration of the recording's release on ECM New Series in 2015, de Mare played the entire collection across a three-concert series at Birdland, the Sheen Center and Symphony Space. The recording was cited on twelve major 2015 "Best of" lists, from NPR and the New York Times to The Washington Post, Daily Beast and San Francisco Examiner and was included as a winner of the 2016 Grammy Award for Classical Producer of the Year.

"Not just inventive piano arrangements of the songs but new compositions written in the composers' own styles... It was fascinating to hear how [each] composer approached the song... I loved it."
