I listen to BBC Radio nan Gàidheal and every now and then they play what sounds like some sort of traditional (Celtic?? / Gaelic?) group singing. It's usually quite slow paced and led by a male singer, with a (mainly female??) group following. There's something slightly depressing, yet soothing about it
I don't speak much Gaelic (yet) so can't understand what the presenter says after it's been played. I'd love to know more about it!
