Trinitones is an all-male a cappella ensemble from Trinity College Dublin, Ireland. Founded in 2012, the group were described as "pioneers" of the collegiate a cappella genre in Ireland in a 2013 University Times article.
In February 2013, the group released a cover of Wheatus' "Teenage Dirtbag", which achieved overnight viral success on UA-cam and led to Twitter recognition from Wheatus themselves as well as performances on The Morning Show on national broadcaster TV3. Since this inaugural release, the group have gone on to produce other recordings and music videos of a cappella covers.
In terms of structure, the group resembles a small male-voice chamber choir of approximately 14 members, featuring bass, baritone, tenor and countertenor parts in addition to a vocal percussionist. Membership is open to current students of Trinity College with auditions held in Fresher's Week of the Michaelmas term.
The group have toured Ireland, the UK, Hungary, Canada, the United States, and Australia, as well as performing in Ireland. They have appeared at Electric Picnic and the Trinity Ball.
