composed The Olympic Reel for the closing ceremonies of the 1996 Summer Olympics in Atlanta, Georgia. It premiered in front of 100,000 people at Centennial Olympic Stadium, as well as 3.5 billion people from the television viewing audience. In 1997, O'Connor and others composed and performed music based on folk melodies as arrangements for the American Revolutionary War-era Public Broadcasting Service documentary miniseries, Liberty! The American Revolution (the companion album is Liberty!). The theme music for the miniseries is O'Connor's Song of the Liberty Bell. In 1999, he recorded his Fanfare For The Volunteer with the London Philharmonic Orchestra for Sony Classical, and one of his most critically acclaimed orchestral pieces American Seasons, which alludes to The Four Seasons (Vivaldi), for Sony Classical as well. "American Seasons", and his "Strings & Threads" Suite (1986) was performed by The Metamorphosen Chamber Orchestra in 2001 at the Great Performers concert at Lincoln Center for the Performing Arts. In a review by The New York Times, "if Dvorak had spent his American leisure time in Nashville instead of Spillville, Iowa, his New World Symphony might have sounded like this." Both "Strings & Threads" Suite and "American Seasons" were recorded for the album The American Seasons, released in 2001 on the label OMAC Records. In 2008 O'Connor paired up with violinist Nadja Salerno-Sonnenberg to record his "Double Violin Concerto" with Marin Alsop and the Colorado Symphony Orchestra for OMAC Records. Over a period of five years, O'Connor teamed up with jazz musicians Frank Vignola and Jon Burr for a trilogy of "Hot Swing Trio" albums dedicated to his mentor Stephane Grappelli. O'Connor recorded Thirty-Year Retrospective in 2003 with the mandolinist Chris Thile, guitarist Bryan Sutton, and bassist Byron House. It celebrates his thirty years as a recording artist on his own OMAC label. He also provided the soundtrack to a 30-minute animated film on the story of Johnny Appleseed (and released the music on his 1992 album Johnny Appleseed), narrated by Garrison Keillor. He contributed four tracks to a 1993 album on the theme of The Night Before Christmas, narrated by Meryl Streep. His composition, Appalachia Waltz (appearing on the album of the same title), has been adopted by Yo-Yo Ma as part of his live performance repertoire, and used frequently as music for weddings including two of former Vice President Al Gore's daughters . One of his chamber music efforts is his piano
