I think I'm going to start a 'new thing' right here, right now and award each show a score out of 10 to help you work out whether it's worth your bother listening. I may not be the most objective judge imaginable - this could be akin to allowing Idi Amin to choose World Dictator Of The Year back in the day - but I'll do my best to be honest and self critical.

This week's show scores an 8.75.

Despite a few fluffed lines from me (and who other than my own mother* cares about that?) / a skipping Los Campesinos track (my CD-R, not their fastidiously manufactured & excellent new album), it's nigh on perfect - containing, as it does, new Future of the Left (EP out now - buy it to alleviate all wan); new Bastions (LP out now - buy it to alleviate torpor); new Shy & the Fight (can't buy it now cos it's not due til 2012).

I'm so happy Future Of The Left have something new out. There isn't enough bristling intelligence in the modern world - well, there is, it's just the karaoke idiots, the finely considered hair dos and the scrotum-munching ITV wannabes tend to be the dead wood, when what most of us are seeking is Juno 60-mangling, lyrically astute TREES. Polymers Are Forever is to wit and noise what owls are to wit and woo.

Get in there, music lovers. Elbow-deep.

The last 15 minutes of the show is dedicated to the curiosity and vision of West Wales' Jobina Tinnemans. She was recently invited to be one of the electronic composers in residence at the Daphne Oram exhibition in the Science Museum (London). She has an all encompassing love for electronic sound generation, and a real vision and gift as a composer, as is magnificently demonstrated by her composition Shakespeare And Hedgeshear.

It blew my mind open in the most effulgent manner imaginable. I hope it does the same for you; widened ears are a very good thing. Ask a mouse.

Elsewhere, there are walk on parts for Huw Williams (troweling down Peter Harvey); Lara Catrin (translating Heather Jones) and Ben Hayes (inspiring us with Jellyfish.)

There are debut plays for Kayla Painter (edgy electronic minimalism); Bertel Haugen (joy encrusted song jewels) and Flying F M (baffling scat).

I couldn't access the BBC Introducing Uploader over the weekend, apparently my security certificate has expired. It'd be easier to waltz into Fort Knox with a bulldozer and a trailer marked 'Gold Swag'. So, for the time being at least, please direct demons and demos to: themysterytour@gmail.com as a download link / high quality .mp3. Please read the below in advance of submitting music.

• Submitting music to the show part one
• Submitting music to the show part two
• Submitting music to the show part three
• Submitting music to the show part four

They're long. I'd give them an 8.75, though. I'm nothing if not consistent.

That's it for the verbals. Please share / retweet about the iPlayer link, not because I'm desperate for a boost -- I'm desperate for as many people as is possible via the 'magic' of social networking, to hear some of these amazing sounds.

Thank you for your time / diolch yn fawr iawn. Have a musically satisfying week, Adam.

* my mum's just been in touch to tell me she doesn't care either. Aces.
