Absolutely amazing 'contemporary Welsh folk music' from the early 1970s. Galwad Y Mynydd (The Call of the Mountain) was a group formed by teenage brothers who went on to record one obscure LP which was re-issued via the Finder's Keeper's label in 2007. Great amateur vocal harmonies, totally perfect home-recorded vibe on the drums and jangly psychedelic guitars make for a really engaging listen.
