His choral compositions are performed throughout the United States and abroad in concert halls, churches, schools, and on radio, television (and YouTube!).  He is best known for his arrangement of the Kenyan song Wana Baraka. The Los Angeles Master Choralehas often presented Kirchner's choral works in concerts at LA's Walt Disney Concert Hall, and commissioned his 2007 setting of the Pablo Neruda sonnet, Tu Voz and his most recent concert suite, Behold New Joy: Ancient Carols of Christmas.  The Master Chorale's final concert of the 2009/2010 season featured a premiere of his "bluegrass triptych," Heavenly Home: Three American Songs,which received praise in the LA Times as "effectively" written works of "sophistication." Kirchner's pieces are published by Boosey & Hawkes, Oxford University Press, Santa Barbara Music Publishing, and Shawn Kirchner Publishing (available through this website.)


In addition to composing, songwriting has become a career focus for Kirchner in recent years.  His songs combine emotional warmth with carefully crafted lyrics, and are written in a range of styles including bluegrass, folk, country, gospel and jazz. Kirchner's bluegrass and country songs can be heard on the CDMeet Me on the Mountain, and his original jazz tunes are featured in club and concert performances of the Shawn Kirchner Quartet.


Kirchner also maintains an active performing career as a singer and pianist.  A tenor with the Los Angeles Master Chorale, he sings regularly with the Chorale and the Los Angeles Philharmonic at Disney Hall and at the Hollywood Bowl in collaborations with the world's leading conductors and composers.  In 2013, he was part of the LA Philharmonic's tour to London, Lucerne, Paris, and New York that presented John Adams' staged oratorio "The Gospel According to the Other Mary," conducted by Gustavo Dudamel and directed by Peter Sellars. Under the Master Chorale’s music director Grant Gershon, he has sung in several Steve Reich projects, including two recordings for Nonesuch Records and a performance at Lincoln Center in honor of the composer’s 70th birthday.  Kirchner's solo work with the Master Chorale include singing in a small ensemble with Meredith Monk, as well as solo work in Ariel Ramirez’ Missa Criolla, Arvo Part's Miserere and Perotin''s Sederunt principes. Kirchner's work as a pianist includes many appearances with the Master Chorale at Disney Hall and on tour as well as free-lance work in recitals, concerts, and studio sessions.  Before moving to the Los Angeles area, he was a vocal coach/pianist in Chicago, and played for Neil Rosenshein’s studio at the Lyric Opera’s Center for American Artists.  Initially trained in classical music, his improvisational skills now encompass many styles.


Kirchner's growing list of TV/Film credits includes his work as music director/arranger for the 2004 CBS Christmas Eve special Enter the Light of Life, and his singing on a number of recent feature film soundtracks, includingAvatar, Frozen, The Lorax, Horton Hears a Who, X-Men Origins: Wolverine, X-Men: First Class, Lady in the Water, and License to Wed.
