In 2007 producer Sharon Browne filmed the first ever Celtic Thunder show at the Helix in Dublin, Ireland. The concept was to feature a group of men from Ireland and Scotland, who range in age from 21 to 42, and feature songs that celebrate a common Celtic heritage.

The resulting show included an eclectic mix of songs ranging from the traditional to international hits and some original pieces along the way. The current cast of Celtic Thunder is made up of diverse performers, Emmet Cahill, Neil Byrne, Damian McGinty and Ronan Scolard.

The members of Celtic Thunder are each a powerhouse in both their solo and ensemble songs. Ably backed by the dynamic Celtic Thunder Band, their shows are known for the use of dramatic effects of lighting and choreography as well as a stage set resembling an ancient stone pathway suggestive of those referenced in Celtic lore.

The first Celtic Thunder CD/DVD was released in March 2008 and was simply called Celtic Thunder – The Show. A full US and Canada tour followed in the fall of that year, along with a second CD from the Show called “Act II”. In 2009 Celtic Thunder released their second DVD third CD “Take Me Home.” This was followed by “It’s Entertainment” in 2010, which paid homage to US pop culture. 3 subsequent releases “Heritage”, “Voyage” and “New Voyage” firmly returned the show to its Celtic roots, stocked full of Irish and Scottish traditional and contemporary songs. The first Celtic Thunder Christmas CD and DVD were also released in October 2010.

Celtic Thunder also took the Heritage show on tour in the US that year. February 2013 saw the show return to the Helix in Dublin to film their 9^th DVD and 10^th CD entitled “Mythology” which presented a perfect blend of entertainment, ideology, and Gaelic spirituality, providing a modern twist on the old Celtic storytelling tradition.
