This week's show is now available via the iPlayer. Please visit the site any time between now and the start of the next programme.

Sorry for the lateness of this information. I got swallowed up in a tide of sickly milk chocolate, an 18th birthday party, and a Science Café trip to the National Botanic Garden of Wales (fantastic!).

So, better late than never, here's all the info on this week's piranha-filled paddling pool of Welsh music. And there are piranha, for this week's show takes time out to celebrate Welsh music with teeth. That is, some of the finest loud and frenetic Welsh music as chosen by (some of) you via Twitter. Thank you for the excellent suggestions (Bastions, Super Furry Animals, Mclusky, Fflaps, Budgie, Anhrefn, Howl Griff & Demented Are Go).

Elsewhere within the three hours, Huw Williams treats us to something truly amazing and mostly unknown from Sunshine Theatre. All we know is that the searing piece of garage psych we play was released in 1971. And that's about it. Please help fill the considerable gaps in our knowledge.

Our resident tweed-wearer, Ben Hayes, paints some typically idiosyncratic Soft Machine all over the airwaves.

And we have oodles of great new Welsh sounds (please see playlist below). Including début plays for: O Femi, Joanna Gruesome, Winter Villains, Raithism, Jauge, Zinc Bukowski, Steff Adams and Hallock Hill.
