As most of you know, the next stage of the Why Pink Floyd release programme takes place on February 27th, 2012, with the release of The Wall as an Experience edition, an Immersion box set, and a collectors 180g double vinyl edition. This afternoon, the finalised (and quite fascinating) track listings of all three versions has been revealed, and we detail these below, along with ordering details for those of you who cannot resist any longer!

The seven-disc Immersion edition box set of The Wall is most likely the version most Brain Damage readers will be hoping to get. It includes a DVD featuring a film clip from the 1980 tour and the "Behind The Wall" documentary, plus, for the first time, CDs of excerpts from Roger Waters' original demos and work-in-progress versions of songs on the final album. Additionally, among these previously unheard versions are David Gilmour's original demos of Comfortably Numb and Run Like Hell. There's also a fascinating early band version of Another Brick part 1, which is starkly different.

The three-disc Experience edition includes a third CD, bringing together a selection of the demos and work-in-progress tracks found on a pair of discs in the Immersion set.

We also now have the final packshot of the Immersion edition - click the thumbnail to the right to see it in more detail - which reveals some of the printed material and other memorabilia that is included within...

The new issue (cover date February 2012) of the US-published Guitar World magazine has a decent amount of coverage of Pink Floyd, heralded by an interesting cover picture of the band.

In the issue, David Gilmour, Roger Waters and Nick Mason tell the story behind the making of Meddle and Wish You Were Here, the two albums that book-ended their critically acclaimed masterpiece The Dark Side of the Moon. Plus, this issue of Guitar World includes a free poster of previously unseen Pink Floyd artwork by Storm Thorgerson, who designed many of the group's album covers and other imagery.

As part of their coverage of the band, they have also published an interview with Storm Thorgerson (recently extensively interviewed on Brain Damage) which is an entertaining read, and can be seen online in full here.

The magazine is available from selected US stores now, priced $7.99, or online from GuitarWorld.com. It will also be available in selected outlets across the world as an import in due course.

Dark Side Of The Moon - A Photographic Exhibition is a special celebration, marking the 40th anniversary of Pink Floyd's first (and quite troubled) first attempted performance of their best-known album, which took place on January 20th 1972 at the Brighton Dome.

The exhibition runs from January 20th through to March 20th, at the Founders Room at the Dome, and is open between 10am - 5pm on Tuesday through to Sunday, each week. Admission is free. Photographer Jill Furmanovsky, a familiar name to many Floyd fans, spent considerable time on the road with the band including the debut DSOTM gig in Brighton. The exhibition will display a range of these, along with other rare and intimate images by Storm Thorgerson, Colin Prime and Tony Collins. Rock Archive limited edition prints will be available.

On the opening evening, there will be the rare opportunity of a Q&A with Jill Furmanovsky, again being hosted in the Founders Room in the Dome. This (free) event starts at 7pm, and having spoken to the Dome this morning (December 30th), ticketing information should be available in the new year.

BBC Radio 4's Front Row on Monday evening at 7:15pm takes a look at unreleased music. Presenter John Wilson talks to musicians including Kate Bush, Brian Wilson of The Beach Boys, Nick Mason of Pink Floyd, Ray Davies of The Kinks and Nile Rodgers of Chic, as they re-visit old recordings, re-assess the out-takes left in the vaults and consider why some tracks - and even complete albums - lie unreleased for years.

BBC Radio 4 can be heard on FM and DAB radio, digital cable, satellite and freeview, and via the BBC website where they have the excellent "Listen Live" and "Listen Again" facilities, allowing you to hear the broadcasts for up to seven days following transmission. Our thanks to John Myles for the info.
