Andrew Hozier Byrne was a member of ANÚNA from 2007 until 2012. He toured Ireland the Netherlands and Norway with the group sang the lead solo on the recording "“La Chanson de Mardi Gras” as part of the group also singing solos on stage as part of the ensemble during his tenure with it. He participated in the 25th Anniversary performance of ANÚNA at the National Concert Hall Dublin singing lead solos on “La Chanson” and “The Raid”.

According to Michael McGlynn “When Andrew auditioned for ANÚNA he was very young, but it was obvious to me that there was a formidable musical ability that I was happy to nurture over a number of years. I was always aware that he was focussed on being a song writer and I built that into all my dealings with him, pointing him in the direction of relevant issues related to song structure that I used myself as he performed my compositions with the group. I get significant enjoyment from encouraging young composers and writers to develop their own artistic output and continue to see that as part of ANÚNA’s mandate.

Lucy Champion worked with Andrew on his posture and breathing over the years and these became more evident in his work with us over time. I think we showed him the benefits of stillness in performance, the ability to withdraw and focus. Andrew was a pleasure to work with and he grew so much as a performer in his time with us, developing into someone that enhanced the group with his insight and presence.”

His most recent involvement with ANÚNA was in September 2013 where he guested with ANÚNA for a performance of McGlynn’s setting of Francis Ledwidge’s poem “August”.

Andrew has stated of his time in ANÚNA.

“I learned a lot about singing techniques, and even composition, from director Michael McGlynn and Anúna. I also got the chance to tour Norway and Holland.” from Golden Plec

“I love the sound of voices singing together, congregational singing, anything like gospel, or folk, or sea shanties. I spent quite a bit of time in choirs growing up, and in the world-touring music group, Anúna. It's a sound with very rich texture, voices singing together” from mtv.com
