There are a great many I've never heard of either (includingY Tebot Piws!) although I know some of the bands by name I haven't necessarily listened to their music. Perhaps it's time I got to know these people and their music.
Top 50 Welsh Songs Ever?
The Western Mail has published a list of top Welsh songs on www.walesonline.co.uk/topsong .
The list includes Mae Rhywyn Wedi Dwyn Fy Nhrwyn by Y Tebot Piws (on everyone's list I think) and, of course, the great Hymns & Arias. I quote: "You couldn't get more Welsh than Max Boyce if you carpeted your house with turf from Stradey Park while watching endless looped screenings of Grand Slam, eating cawl and shouting 'Over by there, mun'. And you can't say fairer than that.
