Amanda Palmer and Neil Gaiman will guest edit an issue of the New Statesman on 28 May, with the theme of “saying the unsayable”.

The guest-edit will be accompanied by an event at the Hackney Empire, which has already sold out.

Palmer is a ground-breaking musician and the author of the bestselling book The Art of Asking, which began as a TED talk which has received 6.8 million views. She discussed some of the issues raised - about the evolving relationship between artists and their fans - in this New Statesman piece from 2013.

Gaiman is an award-winning writer of novels, short stories, comics and television; his books Coraline and Stardust have been turned into films, and he has written two acclaimed episodes of Doctor Who. In 2013, he was interviewed by Laurie Penny for the New Statesman, which you can read here.

The issue will address the ideas of censorship, taboos, offence and free speech, and contributors include Art Spiegelman, Michael Sheen, Kazuo Ishiguro and Stoya.

Helen Lewis, deputy editor of the New Statesman, said: “Together and separately, Amanda Palmer and Neil Gaiman are two of the most talented, innovative and unpredictable artists in our culture. In the wake of the debates around Charlie Hebdo, 'call-out culture' and hate speech online, and with so many governments around the world repressing their citizens' ability to speak freely, this issue is incredibly timely.”

Amanda Palmer said: “As a long-time devourer and admirer of the New Statesman, it’s thrilling to be able to curate an issue like this. We’re aiming to make it read like the footnotes to a great dinner party with an eclectic bunch of friends - where politics collide with art and economics collide with human feelings. I hope the New Statesman folks don’t regret giving over the wheel of their respectable vehicle to the artists, as we tend to drive off-road . . . but hopefully we’ll at least crash somewhere interesting. Neil and I have been working together (sometimes side-by-side, sometimes on opposite sides of the planet) to make this a real reflection of who we believe, who we trust, who we’d want over for wine at our place to discuss the state of things.”

Neil Gaiman said: “I persuaded my slightly baffled parents to get me my first subscription to the New Statesman when I was 12. I was willing to put up with the political writing, and the people who wanted to change the world * because I loved reading the competition results in the back: I liked watching people playing with literature. And I liked the points of view. I still love the New Statesman, although I'm slightly more interested in the political writing these days than I was when I was 12.

“Guest editing an issue with Amanda Palmer has been a delightful, strange, occasionally frustrating, never boring process. We have agreed and we have argued and we have carved out our respective territories. Fortunately our interests overlap, along with our desire to curate a conversation about the things people do and do not talk about, the things we can and can't say, the culture of offence vs. the notion of free speech... and then there's rock, literature, refugees and so many other things. We have as many points of view as we have contributors (and a motley and glorious bunch of contributors they are). ”

Previous guest editors have included Rowan Williams, then Archbishop of Canterbury; comedian Russell Brand, whose essay on why he was not voting went viral and led to his appearance on Newsnight; Chinese dissident artist Ai Weiwei; Jemima Khan, who sent Hugh Grant undercover to investigate phone hacking; and Grayson Perry, who coined the influential term “Default Man”.

The issue will go on sale on Thursday, 28 May, and will also be available on iPad and Kindle. You can pre-order a single-issue by emailing sbrasher @ newstatesman co uk
