On Thursday, April 13th, there will be a one hour radio special on the new Deep Purple album inFinite with interviews with Ian Gillan, Roger Glover, Ian Paice, and Don Airey, plus several tracks from the album. The show is on the air between 9 and 12 pm with the Deep Purple special in part two. It will broadcast on GTFM in South Wales, BCFM in Bristol, and online at Rock Radio UK.
[Update Apr 15] The show did not contain live interviews, but rather prerecorded comments from the band that were distributed by the record company and you may have heard elsewhere.
Listen to the show (Purple segment starts about 5 minues in)
Thanks to Andy Fox and Nigel Young for the info.
