Pink Floyd's official Facebook page are this week canvassing the opinion of fans around the world. As we all know, the band have played some very notable concerts over the years. A number of fans (including a few of us from BD) have deliberated on this to come up with a shortlist of ten key shows, selected on the basis of great performances, or for being significant for various reasons, and they'd like you to vote on them to determine the show that you would most like to have attended (or the best gig you did attend, if you were so lucky!).

They are asking for you to rank their top 10 in order; all 10 will be listed and you will be able to drag and drop them into your own preferred 1-10, and then submit it. You've got until Friday (October 14th) to do this, and as part of this, they have a prize up for grabs of a signed Wish You Were Here fine art print for one lucky entrant in their "check-in challenge".

For more details, and to see the shortlist and vote, visit the Floyd Facebook page and click on the Wish You Were Here tab on the left hand side, or click here to go directly to it.

UPDATE: Voting has now closed and on Monday (October 17th) the gig which ended in tenth place was announced...the Royal Festival Hall, April 14th 1969 show. The Facebook app shares pictures, music, the set list and other information about this concert - and will do for the rest of the top ten as and when they all get announced.

At last, the news we know that a number of you have been keenly waiting for. This afternoon, official confirmation has come through of the revised dates for the Brazilian leg of the Roger Waters The Wall Live tour of 2012.

The dates were moved due to incredible demand in Argentina for tickets to the shows there in Buenos Aires, and so here are the confirmed dates in Brazil:

Tickets for all four shows go on sale soon through Ticketmaster.com.br.

London's Idea Generation Gallery are hosting BIG & SMALL, a brand new exhibition of the album cover art of Storm Thorgerson, later this month. Opening to the public on October 21st, and running until November 13th, Big & Small illustrates the vast diversity of format now facing music designers, from billboards to digital downloads and postage stamps. In particular, the show features enormous high quality fine art prints at 5-foot square that are by far the biggest they have ever attempted, of album covers from Pink Floyd, Led Zeppelin, Muse, The Mars Volta et al derived from original art and individually supervised.

The exhibition will also display more manageable sized prints of recent StormStudios work including Pendulum, The Wombats, Younger Brother alongside more familiar works from Black Sabbath, Peter Gabriel, Steve Miller, Pink Floyd and Led Zeppelin.

Idea Generation were the hosts of the excellent Syd Barrett: Art and Letters exhibition which took place in March/April this year. The presentation of that exhibition was a great showcase of Syd's artistic endeavours, and we're expecting great things from Big & Small. We'll be reporting back from the launch evening, so will reveal more then. The new exhibition includes interactive installations that allow members of the public to make and take their own versions of certain album covers. Live events will also take place throughout the exhibition making this a truly immersive experience.

The Idea Generation Gallery is at 11 Chance Street, London E2 7JB, and more information can be found at their website: gallery.ideageneration.co.uk.

The 2011 remasters of Pink Floyd's albums have dominated the album charts worldwide, with key releases making the biggest impact. In the UK, for example, the official album charts have The Dark Side Of The Moon as a re-entry at number 11 (celebrating 557 weeks on the UK chart), Wish You Were Here at number 43, The Wall at number 44, Animals at 88, and Meddle at 99.

In the US, six Pink Floyd albums re-enter Billboard's Top 200. TDSOTM is at number 12, The Wall at number 40, Wish You Were Here at 71, Animals at 83, Meddle at 174 and the Discovery Box Set has a separate entry at number 175. The Billboard Top Catalog chart has Dark Side at number 1 (for the first time since the 2003 Hybrid SACD peaked there), The Wall at 5, Wish You Were Here at 6 and Animals at 7.
