This week's show is now available on the BBC iPlayer. Please visit the link any time between now and the start of the next programme to listen again.

The only real challenge presented by the move to Saturday nights is how I manage to re-jig my week so that my brain and mouth are in tip-top, athletic condition for a Saturday night. It's fair to say I still have some work to do in this respect. I'm a little like a foreign footballer coming over to the Premier League, having to acclimatise to the extra pace, physicality and paparazzi.

Or, any of Liverpool's recent domestic acquisitions.

So, I'm a little horse-voiced (yes, 'HORSE'-voiced) after a karaoke-blighted Christmas 'do' for the place I DJ in - a very messy affair. I can say with some confidence that the music really did die the moment I strangled American Pie. Again. And again. And again.

Fortunately this week's show is again so brimful of Welsh creative ace the messenger's failings can easily be ignored.

There are début plays for: Hot Chelle Rae, Local, KeyMono, The Keep, Hot Damn, Z-List non Entity, S.A.M. Official, Blaidd, Olympians, A La Fiste and Dinosaur Garden.

Demos/new releases/all correspondence should be sent to themysterytour@gmail.com.

Elsewhere Alan Holmes introduces us to the notion of 'harsh ambient', an interesting contradiction and a fascinating piece of music.

Ben Hayes jousts with Don Preston. Pity the poor horse.

Have an excellent, music-filled week, many thanks/diolch o galon.
