Big Finish announced its final contribution to the Doctor Who multi-platform adventure Time Lord Victorious with a new limited edition vinyl titled Echoes of Extinction starring David Tennant and Paul McGann.

Echoes of Extinction features two separate adventures that listeners can play in any order to form a greater narrative.

The double-A side vinyl features a the eighth and tenth Doctors on each side and will be released on split red/blue vinyl.

The synopsis:

Trapped, a haunted monster waits to consume new victims. It needs help. It needs a doctor. Unfortunately, it also needs to kill whoever it meets. Thrust into immediate danger, and on the back-foot, it will take all of the Doctor’s ingenuity to triumph. Two interlinked adventures. Two Doctors. One foe.

The supporting cast includes Arthur Darvill (Doctor Who, Broadchurch), Burn Gorman (Torchwood, The Expanse), Mina Anwar (The Thin Blue Line, The Sarah Jane Adventures), Kathryn Drysdale (Benidorm, Two Pints of Lager and a Packet of Crisps) and Paul Clayton (The Crown, Him and Her).

David Tennant said:

“The Doctor in Time Lord Victorious is a different character. He’s slightly lonelier, slightly scratchier, when he doesn’t have one of his pals to hold him back.

But it’s nice to tell stories from different times of his life. You just have to try and make sure you’re in the right mindset. The script is fascinating. I’ve only got one side of it, but I’m very aware there’s more to this story, that there’s another Doctor on the other side of the disc. I look forward to getting my LP so I can listen to it all.”

Paul McGann said:

“I’ve read this script twice through and I’m still none the wiser. I’m more confused after the second time than I was after the first. It’s only while working on it that I’ve become aware of how it’s going to be structured.

It really appeals to me, the idea that it’s in two parts, on two sides of vinyl. I think it’s fun for people listening. Part of the excitement is when the different incarnations meet… or nearly meet.”

The vinyl will launch in selected UK ASDA stores on November 27.

A digital download of the story will be released on December 4, and is available to pre-order for £8.99.
