The repertoire of the Brothers is very broad and includes old Dublin street songs, music hall songs and historical ballads, songs from the Irish, English and Scottish traditions, along with songs by contemporary writers. Shay and Michael are close harmony singers, with a special fondness for songs that include their audience in chorus, and many of the songs are narratives with stories. The performances include a lot of up tempo reels and jigs, along with some mighty fine dancing from their dances, which brings an added excitement to every concert. With each show interspersed with stories, jokes and humorous childhood anecdotes, audiences invariably leave their concerts smiling broadly and humming new choruses.

Shay and Michael Black are now touring the U.S. regularly. Piano player, Bryan Seet, and cellist Myra Joy, accomplished solo musicians in their own right, have been in the Black Brothers Band for eight years, and are now joined by fiddle virtuoso Bobbi Nikles. Irish step dancer and accordion player, Aislin Roche (ex-San Francisco Rose of Tralee) rounds out the six-piece band to bring energy and liveliness to the music.
