The Contemporary Music Centre in Dublin has a useful catalogue of festive choral music with Irish connections, which can be viewed on its website. Ranging from unison to 8 part voices, and from the easily accessible to the challenging, there's something here for any choir looking for something a little different for its next carol concert. All of the items are available direct from the Contemporary Music Centre.
Several of the carols were commissioned by RTE and Lyric FM for their Carols for Christmas competition. Other delights include carols in Irish and English, a chorus with optional vibraphone, a pagan carol, and a carol inspired by the chorus of the 2003 Grammy Award winning Hey Ya!
Truly something for everyone.
