Back in 1987, Irish composer Michael McGlynn founded Anúna, a vocal ensemble spanning the boundary between classical and Irish traditional music, with a modern, almost New Age twist in many of their performances. Thirty-two years and eighteen albums later, they're still going strong. You can read more about them at their Web site.
I've picked four of the ensemble's songs from their very extensive portfolio. First, here's "The Rising of the Sun", from their 2002 album "Invocation".
Next, a modern and rather different setting of an old Irish ballad, "Dulaman". This version is from their 2010 compilation album "The Best of Anúna".
For a change of pace, here's a medley of the traditional English folk songs "Greensleeves" and "Scarborough Fair". Both songs were covered separately on their 2014 album "Illuminations".
And finally, here's "Wind on Sea", also from the album "Invocation".
You'll find much more of their music on the group's YouTube channel, and on Amazon.com.
