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

The show ties a knotted hanky around its head, strips down to a very fetching string vest, and revels in a selection of some of the finest, summery Welsh songs EVER, as chosen by (some of) you. So I get an excuse to play a bit of vintage Gorky's, MC Mabon, Crashland and Topper./p>

Next week the Twitter jukebox chooses a playlist of the greatest, loud and frantic Welsh songs. Already we have requests in for: Demented Are Go, Budgie, Flyscreen, Mclusky, Midasuno, Anhrefn, Exit International... tweet your choices to twitter.com/welshmusic or leave a comment here. Make them loud, of course. I want to shake the airwaves until they crumble into a cloud of foul-smelling dust.

But the lifeblood of this show is the new music we get to unearth, and this week we have début plays for Poppy Jones, The Tapestry, Chloe Leavers, Mortalpsycle and Jewellers. It's like Kenny Dalglish's youth policy at Liverpool manifested in sound. And with better gender representation.

Pretend I'm a hungry seal and that your new releases & demos are juicy fish. Throw them into my hungry, barking mouth via themysterytour@gmail.com (mp3s/download links) or in the post:

BBC Wales,
Canolfan y Diwydiannau Creadigol/The Centre for the Creative Industries, Prifysgol Glyndwr/Glyndwr University,
Wrecsam/Wrexham
LL11 2AW

We also have very exciting plays for new genius from Future Of The Left, Georgia Ruth, D. Gritty, Underpass... the playlist is below. It sounds 1,000% better than it reads. Not one for exaggeration, me.

Elsewhere the godfather of the Welsh underground, Alan Holmes, reminds us of the (excellent) TGT; Ben Hayes treats us to the first ever single boasting a dedicated fuzz circuit, and Lara Catrin translates Y Trwynau Coch.

Enjoy the sun! Have an excellent Bank Holiday.

Adam
