BBC Radio 4, in conjunction with John Harris (author of the DSOTM book), explore the tragic breakdown of Syd Barrett, and how his fellow band members and family coped, in a repeat airing of a programme originally broadcast in June 2011.

The Twilight World Of Syd Barrett airs again tomorrow (Thursday, May 3rd) at 11pm - 11:30pm. Band members reveal the concerns they had when he began to go catatonic on-stage, playing music that had little to do with their material, or not playing at all. By spring 1968 Barrett was out of the group but he re-emerged in 1970 with a pair of albums, which failed to chart. Barrett retired to a hermit-like existence under the watchful gaze of his sister Rosemary.

The programme includes interviews with Rosemary, as well as David Gilmour and Nick Mason, plus one of Rick Wright's final interviews before he died. Band members describe how there was then little understanding of mental illness and that steps taken to help him might not have been appropriate.

BBC Radio 4 can be heard on FM and DAB radio, digital cable, satellite and freeview, and via the BBC website where they have their "Listen Live" and "Listen Again" facilities, allowing you to hear the broadcasts for up to seven days following transmission. Our thanks to Malcolm Walker for tipping us off about this show's repeat airing.

Just released is a ten minute documentary called "The Missing Piano". Billed as "a behind the scenes glimpse into the making of the Wish You Were Here SACD", it features James Guthrie talking about the recently released multi-track Super Audio CD of Pink Floyd's 1975 classic. We investigated this release in depth here, including an interview with Guthrie. If you've not yet read it, it's worth checking out.

The documentary is a short, but interesting look at the background to the project. There's a segment talking about how a missing piano piece by Richard Wright was investigated, and you hear this piece highlit on the soundtrack. Elsewhere, Storm Thorgerson talks about the packaging for the new edition, and explains how they came up with the idea to return the original pictures to the elements represented. So, the picture of the burning man gets burnt itself, the splashless diver picture is itself under water, and so on.

You can view the documentary on Youtube, and we've also embedded it here:

To celebrate the upcoming 30th anniversary of the motion picture 'Pink Floyd: The Wall', on-set stills photographer David Appleby is honouring the fans of the acclaimed visual rock masterpiece, with an exhibition of stunning behind-the-scenes images taken during the production of 'The Wall'.

On display, there will be over 40 traditionally and painstakingly hand-printed black and white silver gelatin prints from the original negatives, by Silverbase of The Photographic Centre which is within the legendary Pinewood Studios - where some of the film was shot. Other images are due to be displayed too.

Brain Damage has had an exclusive preview of the pictures involved, and we know that those who are able to attend will be in for a treat. There are some wonderful, intimate moments, along with iconic moments from the production but from a unique perspective. Most have never been seen before, having been discovered lurking in a store room at Pinewood since they were originally shot.

The exhibition will be at Blackall Studios in Shoreditch, London, between July 13th-18th, shortly before the 2012 Olympics hit the capital. The private view of the exhibition will strive to raise plenty of cash for the charity "Medicinema", and to get fans worldwide involved, Indigogo is doing a fund raiser to put on the exhibition. Every donation towards the exhibition will get various special (and exclusive) rewards, such as prints, posters, and the exhibition catalogue signed by David Appleby. Should the exhibition be a success, plans are to take it worldwide. Any galleries interested should get in contact with us and we'll pass on your details!

We'll keep you fully updated on this exhibition, and will be reporting from the opening evening. Watch this space...

At the start of the month, we gave you details of the upcoming "Pink Floyd: The Story Of Wish You Were Here" Blu-ray and DVD. Released by Eagle Vision HD, the title is coming out on both formats on June 25th in the UK, and June 26th in North America. Other areas should follow suit around those dates. Much anticipated, we've had a lot of emails from people in various places wondering when they'll be able to get their hands on it.

With a quoted runtime of 85 minutes, this programme tells the story of the making of this landmark release through new interviews with Roger Waters, David Gilmour and Nick Mason and archive interviews with the late Richard Wright. Also featured are sleeve designer Storm Thorgerson, guest vocalist Roy Harper, front cover burning man Ronnie Rondell and others involved in the creation of the album. In addition, original recording engineer Brian Humphries revisits the master tapes at Abbey Road Studios to illustrate aspects of the songs construction. The DVD and blu-ray releases contain additional bonus material not featured in the TV broadcast version, including further interviews with Roger Waters, David Gilmour and Nick Mason, plus Roger and David performing excerpts from the Wish You Were Here album.
