You might recall our story from 5th January about the wonderful imagery that was projected during Roger Waters' world premiere live performance of Ca Ira, in Rome in mid-November.

Those that were there, or those who read our concert review and looked at our gallery of pictures, will have been struck by the thought-provoking pictures that were projected onto the screen behind the black-clad orchestra.

Just a bit of advance notice for you - next week, Roger Waters further explores his foray into the world of classical music, by taking part in a documentary about Mozart.

A recent report in the Wall Street Journal hints at the possibilities that rare Pink Floyd concert recordings might be on the horizon.

The recordings are part of an archive of more than 5,000 live audio and video tapes made between 1966 and 1999, and only recently discovered when Bill Sagan spent over $5 million to buy up the Bill Graham Presents collection, which was lying unwanted and uncatalogued in a warehouse. Some of the collection was even damaged by a fire.

Friday morning, former Pink Floyd frontman Roger Waters was interviewed on the BBC's HARDtalk Extra, in a fascinating 23 minute chat.

The show was broadcast in many countries on the BBC World TV channel, and in the UK on BBC News 24. For all those who missed the show, we now have details of how you can view the full interview via the BBC website.
