After determining production requirements for David Gilmour's 2016 North American Tour, which normally means the stage/lighting/speaker layout has been finalised for the venues involved, there will be extra seats released for both Hollywood Bowl concerts, which are due to take place on March 24th and March 25th 2016, and kick off the 2016 tour.

These concerts are both currently sold out, so this will be good news for those who missed out when they originally went on sale.

The extra tickets across both dates will be available for sale tomorrow, Saturday 12th September, at 10.00am local time. Ticket buyers will be among the first to receive the new album, as every ticket purchased online will include a redemption for a Rattle That Lock CD.

With apologies for the short notice, the UK's BBC Radio 4 Front Row programme which airs at 7:15pm this evening, includes an interview with David Gilmour, which was conducted during the final production rehearsals for the upcoming tour which were held at the Brighton Centre - scene, of course, of the incredible Preview Show at the weekend.

As with other BBC radio stations, BBC Radio 4 can be heard within the UK, and in many parts of Europe and further afield, via FM radio, DAB digital radio, digital cable/satellite TV, and online. In certain places, you can also tune in via long wave and medium wave. You'll also be able to listen to the show in most countries worldwide once aired via this link to the BBC's iPlayer service.

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.
