Welcome to my first Saturday night show on BBC Radio Wales since the invention of the internet.

All the little melodramas associated with swapping a music show from a Sunday to a Saturday night were put into crude perspective just before I went on air. I heard that a friend had passed away. A friend who is synonymous with Newport in the early - mid 90s. That was a time and a place that will always be close to my heart: it's when I started making radio shows, and the music that came out of Newport then is still some of the most exciting I have ever heard.

And whenever I went down to Newport - which was often, back then - to see 60ft Dolls, or Five Darrens, Novocaine, Rollerco, Flyscreen or D*I*S*C*O, Ali Hale's friendly face would be one of the ones that I was most happy to see. For what it's worth, this show is dedicated to her memory, and to her family and friends: far, far too young and ace to leave us.

This week's show features a wonderful session from the Llyn Peninsula's Cowbois Rhos Botwnnog. Their songs sound like embers from an infinite heart. Or a bit American folk, if you prefer something more specific. Three beautiful songs that'll make you yearn for prairies and horizons you've never seen.

Alan Holmes reminds us of the organic, avant garde artistry of Graham Bowers, whose recent collaboration with the legendary Nurse With Wound glories in the possibilities at the edges of the map.

Lara Catrin translates something wonderful from Georgia Ruth.

And Ben Hayes shows up my ignorance of key cogs from the mid 60s engine room.

Either that, or I'm a very convincing devil's advocate. No? Oh, I didn't think you'd buy that. Pfft.

Elsewhere there is much music. Including a rather non-standard piece of broadcasting (Irma Vep) - I'll blog about that in more detail before the end of the week. We have debut plays for Jasper, Anatomy Of The Bear and Idol Heart Beats... if you have fascinating tuneage for us, please send it ASAP as a download link/mp3 to themysterytour@gmail.com.

Have an excellent, music-filled week.
