The Trinity Singers piece for LookListen is called "Sleep". Intense and atmospheric, Sleep is the most famous work by American composer Eric Whitacre, whose distinctive chordal writing is hugely popular with choirs all over the world. Whitacre creates clouds of harmony, forming frothy textures unreliant on melodic movement. The broad dispersion of voices gives an impression of depth and vastness, well suited to a choir of the size of Trinity Singers.

Trinity Singers has traditionally been the small mixed chamber choir of Trinity College in Dublin. However, in recent years, interest has surged and the group now brings together approximately sixty diverse and committed singers from across all faculties of the university, including engineering, medicine, arts and science. The choir rehearses once a week during term, and as well as preparing for its own end-of-term concerts, occasionally joins forces with other student societies such as the Trinity Orchestra for charity performances and college events.

Trinity Singers is conducted by Róisín Blunnie, a postgraduate student in the Department of Music.
