Ever since performing for the first time publicly, Finbarr has continued to appear in the concert hall regularly. He has performed at venues such as the Wigmore Hall, St. Martins-in-the-Fields and the Royal Exchange Theatre to name but a few. Finbarr has also performed in a number of festivals including the Walton festival, the Bowdoin music festival in the USA where he was a teaching assistant and the Rye festival in East Sussex. In many of his recitals, Finbarr has performed an eclectic mix of music. His performances have included the works of J.S. Bach, John Dowland, Benjamin Britten, William Walton and Manuel Maria Ponce and most recently he has arranged and recorded the works of Jean-Phillipe Rameau and Domenico Scarlatti.
Another aspect of Finbarr's career has been his desire to play and champion new works. He was involved in the first recording of a composition written for guitar quartet and symphony orchestra by fellow Peabody alumnus Christopher Gainey performing with the Peabody Symphony Orchestra. Finbarr gave the world premiere of two works at the Peabody institute of music in collaboration with the composition department there. He premiered the work of composer and friend, Eric Stewart, in 2014.
Finbarr has extensively performed with a variety of ensembles including the National Youth Guitar Ensemble of England where he performed with legendary guitarist John Williams. During his time at the Peabody, Finbarr performed with the Peabody Symphony Orchestra on a number of occasions. He is currently a member of the Nocturnal Guitar Duo that has gone on to perform across the UK and Europe. He has also been active as an accompanist, most notably accompanying the vocal students of the legendary late English bass-baritone John Shirley-Quirk.
In 2009, Finbarr received his Master of music degree from the Peabody Institute in the US in a prestigious course with combined 5 year Bachelor and Masters of music degrees where he studied in the studio of Manuel Barrueco and was awarded a Peabody scholarship. He was more recently awarded the honour of Artist Diploma in performing from the Royal College of Music, London in 2012.
