Caleb Glickman makes his LA Opera solo debut as the Third Boy in The Magic Flute (January 2009). This production marks his third appearance with the LA Opera, where he performed as a member of the chorus during the 2007/08 season in both Otello and Tosca.

In 2008, Caleb sang with the Los Angeles Children's Chorus in the concert production of Carmen at the Hollywood Bowl, featuring Denyce Graves in the title role. He made his second appearance at the Hollywood Bowl when the Los Angeles Children's Chorus joined the Los Angeles Master Chorale and the Los Angeles Philharmonic in a performance of Mahler's Symphony No. 8, marking Esa-Pekka Salonen's farewell Hollywood Bowl appearance as Musical Director.

Caleb has been a member of the Los Angeles Children's Chorus since 2007, under the direction of Anne Tomlinson, performing in Seattle and in cities throughout Southern California. He began performing in local musical theater productions at the age of six, appearing in the title role in the 2006 production of Oliver! at The Colony Theatre in Burbank. He currently attends the sixth grade at Walter Reed Middle School in North Hollywood and studies piano, violin and flute.
