Eric began as a vocalist and songwriter for a couple of Christian A Cappella groups throughout the late 80s and 90s, and then struck out on his own in 2000. In 2001, he released his first solo CD, a 6-track EP entitled "Refuge" on his own "Spectacle Entertainment" label. Apart from his daughter's "in-utero" heartbeat on the last track, every voice and sound on the CD was performed by Eric, and all the sounds were vocally or anatomically produced.

In 2002, he released 2 more CDs on the "Spectacle" label: "Words of Truth", which is a sampler EP of tracks from his former group, "Q", and "Eric Gwin presents...Songs from the Vault", a full-length compilation CD of rare and unreleased tracks from the groups he's worked with ("Q" and "Ariel").

In late 2005, Eric released his first full-length solo album, "The Calling", which took his acappella musical approach to new heights, venturing into the world of modern rock, R&B, and even hip-hop.

In November of 2007, Eric released "Fresh Hope: Reflections on the Birth of Jesus". It is a collection of 10 original praise-and-worship songs that focus on one of the greatest events of all time-- The Birth of Christ. although it is a full-length album, Eric doesn't consider it to be the "follow-up" to 2005's "The Calling" because it's so different from his other albums.

Currently, Eric is busy working on a follow-up to "The Calling", running his recording studio, "The Cage", and producing projects with other artists for his "Spectacle" label. He also records and performs as one half of the acoustic/ vocal duo "Thirty-Three and a Third" (with songwriting partner David Savage). "Thirty-Three and a Third" released their debut project, a 5-track demo CD, in February of 2004.
