We begin this week's show with a tribute to Les Morrison, a key member of the Welsh musical community, who sadly passed away on Friday 29 April. Les set up Stwdio Les in Bethesda, a facility he would allow the local bands to use for free.

Back at the tail-end of the '80s and the early years of the '90s, studios were expensive and the experience and opportunities Stwdio Les gave to many nascent Welsh talents (including Gruff Rhys & Cerys Matthews) were priceless and key to them getting their music to a wider audience.

Les was a fine musician too, contributing banjo and inspiration to recordings by Super Furry Animals, Gorky's Zygotic Mynci, The Peth, Bob Delyn A'r Ebillion et al. He was also Super Furry Animals' guitar technician. I didn't know Les personally, but everything that I've read about him since his death on Friday speaks of a much-loved, musically intuitive and helpful man.

Our condolences to his family and friends.

Elsewhere in the show, Alan Holmes introduces us to the lyrical acoustic wonderment of Alasdair Bouch's music. Lara Catrin translates something heart-rending from Y Bandana, and Ben Hayes shows us why Bill Wyman's reputation should be more about his musical talents than his penchant for women a third of his age.

We have a selection of bristling, excellent and inspirational new Welsh music including debut plays for Crack Fox, Sleepy Panda Club, Phrazer, Bitform, i-de-ate, Little Nell, Spires & Jay T.
