Produced by Ciaran Brennan, Landmarks doesn't depart from the group's signature blend of Irish folk, Celtic, worldbeat, new age spirituality, and ambient music, but that's hardly a disappointment, since that is what makes Clannad special. With their albums, the pleasure is in the details and there are plenty of details on Landmarks, from the nuances in Máire Brennan's voice to the percolating rhythms of "A Mhuirin O." These flourishes can be heard throughout the album, and that's what makes the album worthwhile for longtime fans.
