Bran presents Irish music to audiences in its full diversity. Their repertoire includes old songs, both in the Irish and English languages, traditional dance tunes, and, if the occasion calls for it, pub music. The "lore" of the melodies is also shared with the audience. Tales, legends and true stories are important add-ins to the music at the concerts. Besides live performances, Bran also offers 'ceilidhs' (dance circles), where a tutor helps those interested in learning traditional Irish dances. The group also organises children's programmes including storytelling, introducing the musical instruments used and creating playgroups.

Bran is on the organisational team of several cultural events, such as the literary evenings with Andrea Závory, Irish Cultural Days organised by the Hungarian-Irish Friendship Association (HIFA), Irish Cultural Summer Camps or the group's Immram Festival. The monthly club-concert is held at Jókai-Klub in Budapest.
