This week's show is now available via the BBC iPlayer.

So, after last week's Half-Term Report on the Best Welsh Noises of 2011 ('so far'), we're back on more familiar, unfamiliar ground this week - three hours marvelling at the best sounds that have most recently arrived in my inbox, including début plays for Dee Shae, Poket Trez, La Decadanse featuring Gwenno (track of the week!), Sion Russell Jones, Falcon Lake, Location Baked, Tegan Newydd, Dirty Sparrows, Sŵnami, The Adelines, Sib, Masters7 and Scribble Man.

Throw new Welsh sounds like fresh fish into the gaping maw of a ravenous seal by mailing mp3s/download links to themysterytour@gmail.com.

Alternatively, the BBC Introducing Uploader is an easy way to scatter your finest tracks to all of the BBC Introducing Shows in Wales (Jen Long/Bethan Elfyn).

Elsewhere Huw Williams dons inappropriate crêpe-soled shoes and sweeps us off to Cardiff in the early '60s, reminding us of the Gary Edwards Combo, who kept the capital twisting before Beatlemania.

Ben Hayes comes in to demonstrate that there was (occasionally) more to Herman's Hermits than music hall comedic chaff. In fact, their album Blaze is something of a forgotten, psych-pop classic. As Ben admirably demonstrates with the track Museum.

Unfortunately, last night's show was interrupted by a network failure between Wrexham and Cardiff which means that two hours 12 minutes in the connection drops and we disappear for a while. Please persevere with us (we do return after a short gap, David Woodward in the Cardiff hub treats us to a little Glow... excellent choice!). This gap in proceedings does mean that all of Lara Catrin's excellent translation of Sen Segur's Cyfoeth Gwlyb is lost.

We'll broadcast that section in full, next week. Sorry for any inconvenience. Special apologies to VJKnievil who got a bit of a fright in his shed in Newport when the connection was re-established.

Our transparent ploy for getting you involved with last night's show was to ask you, via Twitter/text message and e-mail, what your favourite ever gig was. The response was incredible, but - due to the network failure - I wasn't able to round your amazing choices up at the end of the night as planned.

A team of crack IT ninjas is - even as I type this - hunting out the problem. There's nothing quite as reliable as an IT ninja.

Have an excellent week and keep your music/gig info/anecdotes/ace Welsh music requests etc coming.

Thank you/diolch yn fawr iawn,

Adam Walton
