Born Eric Jacobson, Eric Moon has been performing since the age of 8, when he sang the boy soprano part in the second world-premier of George Crumb's "Ancient Voices of Children" with Jan DeGaetani and the Boulder Philharmonic under the direction of David Burge. In the next few years, he won several piano competitions at the state level, and performed with the Boulder Children's Choir in productions of "La Boheme", "Turandot", "Carmina Burana" and "Stabat Mater".  He also served as organist at St. Ambrose Episcopalian Church in Boulder.  As a junior in high school, he was the winner of the Music Teacher's National Association composition contest at the national level. It was at about this time that he began playing piano professionally, backing up Fred Shelton at Fred's restaurant on pearl street in Boulder, CO, six nights a week, and working as pianist for the Stagedoor production of "Now That's Boulder" with "Musician" magazine founder Gordon Baird. He studied for two years at the Eastman school of music in Rochester, where he worked steadily as a jazz musician, including performances with former Coltrane bassist Steve Davis.

Returning to Colorado in 1981, he worked for the vocal group Rare Silk, including the recording of the album "Black and Blue", co-wrote the song "Bob Goes to the Store" with bassist Kim Stone, which was released as a single and video by the band SpyroGyra, performed with Charlie Pride and Bob Hope as pianist for concerts at the well known golf tournament in Vail, and was the pianist for an influential Denver jazz combo led by drummer Bruno Carr, well known for his work with Ray Charles, Ella Fitzgerald, Herbie Mann and others. At this time, he also became involved with the Denver underground rock scene, performing with the progressive rock band "Thinking Plague", and co-founding the band "Legacy of Sorrow" with Ron Miles, voted "Best Art-Rock Band" by Westword magazine in 1986.

In 1987, hired as pianist, arranger and musical director for singer/songwriter Jill Sobule, Moon put together bands for showcases that led to her publishing deal out of Nashville and subsequent recording deal on MCA. Moving to Nashville in 1989, he played and recorded with top studio musicians, including Vince Gill, Flecktone bassist Victor Wooten, and session legends Eddy Bayers and Michael Rhodes. He subsequently played keyboards and arranged the string section for Sobule's first album, produced by Todd Rundgren. In 1992, Sobule hired Moon to co-produce her second album with long-time Prince engineer Susan Rodgers in Los Angeles. That album featured Wendy and Lisa of Prince's Revolution band, and Moon's arrangements for the Tower of Power horn section.  He also played bass and arranged, produced and co-wrote music for singer/songwriter Jane Fontana, including performances at renowned LA venues such as The Viper Room, The Troubador, Club Lingerie, and Spaceland.

Relocated to Los Angeles in 1993, he produced and co-wrote a number one hit for Malaysian singer Ella, composed music for national television ads for Mervyn's and the E! network, toured Europe as keyboardist for German punk icon Nina Hagen, ran the computers on a series of shows for Icelandic superstar Bjork, recorded with Nancy Wilson of "Heart", designed sounds for Alesis Synthesizers, composed music for national cable TV, and recorded backing tracks for the Chippendales dancers.

Moon returned to Colorado in 2000, doing a stint playing piano and accordion with Banjoist Tony Furtado, co-founding the country-swing band "The Dangerfields" with KC Groves and recording and performing with the americana/alt-country band "Buckskin Stallion".  After several years during which he worked as a Computer Programmer in Denver, he moved to Lander, WY, where he taught piano, played drums in the band "Bru Swillaz", and performed as guest soloist with the Central Wyoming Community College Big Band.

In 2004, he was invited to Austin, where he played with members of George Strait's Ace in the Hole band and The Hal Ketchum band, and recorded piano, accordion and hammond tracks for the first solo album by Asleep at the Wheel vocalist and violinist Hayden Vitera.  

Returning home that same year, Moon resolved to commit himself to developing his career in Colorado.  That fall he put together a band for acclaimed Nashville singer/songwriter Jeff Finlin, and recorded with Colorado artists Ron Miles, Danny Shaeffer, Andy Monley and Rhian Ayanna.  In 2005 he formed the instrumental pop band "gogoLab" with drummer Brian McCrae and bassist Bijou Barbossa, and recorded the album "The Stakeout".  He also played organ and accordion for the Ron Miles release "Blossom".  In 2006, he went to Wales to record the album "The Pull" with songwriter Kreg Viesselman. There he met Liz Barnez, with whom he has recorded and performed ever since, including shows in New Orleans and Minneapolis, and at the House of Blues in Chicago.  He also played for the 30th reunion of the Pearl Street Jazz Band, with whom he had performed at the opening of the Boulder Mall in July of 1976.

In the fall of 2007, he performed on the with M'shell Ndegeocello and Steve Earle on the nationally-syndicated radio show 'E-town', and played for a benefit at the Boulder Theater with  Nashville songwriters Darrell Scott and John Cowan.  He also recorded the album "Water on Stone" with singer/songwriter Rebecca Folsom and the E-Town rhythm section.  In the spring of 2008, after being hired as accordionist on George Inai's debut album "This Foolish Music", Moon traveled with George to London to do a series of shows, playing accordion and lap-steel guitar. Upon returning, he worked as accompanist for the Casey Collins Vocal Workshop Intensive in Boulder.  Most recently he has been recording with former John Denver bandmate Jim Salestrom, who performed "Rocky Mountain High" at the state capital on its inception as a state song. Coming up, he will be doing a series of shows with LA vocalist and Denver native Mollie Weaver, performing with Country singer Suzy Boguss and John Denver alumnus Bill Danoff, performing with National Blues Award-winner Lionel Young and recording a new album with Ron Miles.
