This week's show is now available via the iPlayer. One of the (many) resolutions I have drawn up since my 'significant' birthday last week is to be more measured in the language I use when I talk about this show and the music that is contained therein.

'Amazing' loses its power the 400th time you use it in a month, regardless of how much you mean it. 'Awesome' might as well be describing oven cleaner unless it's used sparingly, with a sense of perspective. (New rule of thumb: use the word 'awesome' as often as I use actual oven cleaner... which means, after this single paragraph, the word is out of bounds until 2036.)

How much of the world can, really, be 'beautifu'"? One look in the mirror tells me I'm doing more than my own part to balance that equation... but if I say that everything is beautiful, doesn't it lose its capacity to make us gasp?

Well no, not really.

It doesn't matter much what I say. It's down to the music and what you think about it. I just hope - really hope - that you're as much bewitched by its gloriousness, its amazingness, its awesome power to transform a moribund moment into something charged with excitement. But I should say these things less often, and let the music speak far more eloquently for itself. Shouldn't I?

But that makes luring you away from all of the other distractions you have in your life that much more difficult. Time is precious. It's a sad fact of modern life that we all have to be a little bit double-glazing salesman (nowt wrong with that if you're actually selling double-glazing, of course), a bit X-Factor voice-over (always something wrong with that) to try and attract each others' attention. And I don't want to be like that any more.

Suffice to say, then, that this week's programme features, without fanfare, some boggling creativity from Welsh minds operating in all different kinds of sonic spheres.

Well, I've been well and truly boggled by it.

Consider a first time play for Sam Airey. Within moments of him pouring his soulful, folkish honey onto our airwaves, my inbox and Twitter feed were busy with acclaim and praise for his talent. It's an outstanding piece of music, is his debut single Blackout. No other language will suffice.

There are début plays for Black River (swoon), Laurence Made Me Cry (beam), Ocean Red (overexcited handclaps), The Bear Beats Band (jaw drop at that voice), Black Stepdad (awed bemusement) and Broken Moods For House Kites (beaming smile).

And elsewhere, magnificent new recordings from Metabeats, Channel Swimmer, Dez Williams... heck I'm going to just list all of the tracks I played (see below for more details.)

So, the reason I say things are ace is because they're 'ace'. Where's the fun in being restrained about it? Measured is what happens to you before they stick you in a wooden box, and even I'm not ready for that yet.

If you find a few hours over the course of the week to check the show out, you'll be rewarded with some great music. And that's a fact, not a piece of hyperbole.

Godfather of the Welsh underground, Alan Holmes, comes in to enthuse about Mr's pre-millennial psychedelia.

Lara Catrin translates Edward H Dafis (and in the process disturbs her own sleep, just for you!).

Ben Hayes lyrically waxes the Jan Hammer Group. So much more than the guy who scored no socks and Phil Collins guest appearances on Miami Vice.

I want more of your music, an insight into the music you've been hearing that's amazed you, and to hear what you think about all of these sounds.

Send demos (.mp3's or download links) / releases / thoughts to: themysterytour@gmail.com or via the BBC Introducing Uploader.

My preference is to receive your music via e-mail, but whatever suits you best will suit me too.
