This coming Sunday, September 13th, BBC Radio 6 music is broadcasting a very special show - an hour long interview (with music) with David Gilmour, talking to Radio 6 presenter Matt Everitt about the key musical moments of his life and career.

The interview coincides with the start of the 2015 Rattle That Lock tour, which kicks off the previous day in Pula, Croatia, and is just prior to the release of his new album, which appears worldwide on September 18th.

The show airs at 1pm UK time.

Ron Geesin - An Improvised Life is a new, one hour documentary that explores the life of this remarkable, yet largely unsung, artist through a mixture of live performance, interviews, film extracts and archive material. The film includes never before seen footage of Ron Geesin and David Gilmour at the 2008 Atom Heart Mother concert at London's Cadogan Hall, which featured blistering guitar and pedal steel work from David.

The film has interviews with David Gilmour, Nick Mason, Pete Townshend, Peter Gabriel, Robert Wyatt and Bridget St John amongst many others.

More information on the documentary can be found at GeesinImprovLife.com, and there will be a special premiere event at the Doc'n'Roll Film Festival, at Picturehouse Central, in London on Saturday October 3rd. The screening of Ron Geesin: An Improvised Life will be followed by a Q&A with the Director, Tom McInnes.

Today's Simon Mayo Drivetime programme on BBC Radio 2 (in the UK), from 5.05pm BST, includes an exclusive interview with David Gilmour, and has David selecting his favourite tracks from the upcoming album, Rattle That Lock. The show runs until 7pm and as yet we don't know what time the interview will be aired.

BBC Radio 2 can be heard on DAB and FM radio, via Freeview, Sky satellite and Virgin Media cable, and via www.BBC.co.uk/radio2, which will allow listeners around the world to tune in. The BBC's iPlayer service (at their website, and on Virgin Media) will allow listening on demand for seven days from the date of broadcast, principally for those in the UK, but this does also work in a number of other countries.
