"They were an underground band who started releasing cassettes in 1982 and are from Aberteifi in South West Wales, so they weren't part of a scene. They were from a small, working class town where, strangely, an interesting guy called Malcolm Neon had set up a cassette label, releasing electronic music in the Welsh language. So they kinda fit in – he put a tape of theirs out and gradually they released more albums, which would end up on the Anhrern, a punk rock Welsh language label which John Peel started to play. By the time Pyst came out in 1990, David R. Edwards' voice was becoming the key critical voice of the Welsh language. He held a mirror to society and to himself that was so brutally honest: they weren't embraced by the media at the time because they were misunderstood. They were gradually more acclaimed for their genius as time went on. The name of the band translates to English as 'developing', so they had experimenting as part of their reason for existing. By this time, it was David R. Edwards and Pat Morgan on bass and she brought a really distinctive musicality to the band. Their first two albums had been produced by Gorwel Owen who, for me, is like a Welsh Conny Plank, so everything was experimental but also really well-recorded. And this album [Datblygu] is a mixture of great songwriting. He can – when it's necessary - write a conventional pop song but delivered in a unique way like the classic, timeless songs. We covered one of these, 'Y Teimlad', on the Super Furry Animals' record Mwng. There are some great songs on this record – one is 'Ugain I Un' which is like a generic country and western song about being a horse [running] at [odds of] 20/1 who fails a jump and gets shot before the end of the song. There's another pop song called 'Am' which is just great pop music! But [the album is] always experimental and you could compare David to people like Mark E. Smith, Nick Cave and Allen Ginsberg, people with an honesty and darkness which is timeless as the lyrics deal with basic human traits. This isn't self-consciously Welsh. In fact, it's very critical of Welsh society in the Welsh language as that's the most honest way you could communicate [this idea]. And it captures Wales at that time where there was a great non-conformist musical streak going on ."

"I could name a whole lot of well-known artists from anywhere in the world who have made great records but maybe it's more interesting if I pick up on things that I've grown up with that, for geographical reasons, aren't known much outside this particular Welsh language culture. These records aren't talked about everyday in the English language. Someone like Geraint Jarman, with Datyblgu, might be the most powerful Welsh language music [of its time]. He is from a generation earlier [to Datyblgu] and started releasing solo albums in the mid-1970s. He was part of the folk movement in the late-1960s and was in a band with Meic Stevens and Heather Jones called Baramenyn. They were making almost pastiche folk music that was critical of folk music but the records were really popular! They were almost like Os Mutantes without the fuzz! Geraint was a poet first and wrote really good poems like Gil Scott-Heron. He had those skills which he applied to rock music in the mid-1970s. He also had an amazing band who could record an album in a couple of days and an amazing guitarist called Tich Gwilym. This album is like a mid-1970s rock album but informed by punk - Television are in there, too - but it's got that grounding in songwriting from the folk days as well. You can get lost in the guitar playing as well and the lyrics are risqué for the community he was singing to at the time - Wales was quite a religious place in a non conformist way. But it's not kitsch music, it's very much engaging with its day and Geraint grew up in urban Cardiff in a Welsh speaking family but with connections to the Romany world. Like a lot of bands from elsewhere in Wales at the time, he was part of a multi-cultural society, a lot of his friends from school were in reggae bands and he gradually got more and more into reggae. You can hear this in this record but it's also a rock record. By the end of the 1980s, he was playing at Reggae Sunsplash so it's interesting...he was still [singing] in the Welsh language! He's still singing and putting records out. He also pioneered a Welsh television show called Fideo 9 which was like Snub TV or something and he put a lot of energy into that. He was also the voice of the cartoon character Super Ted!"
