Pink Floyd’s David Gilmour has said that he’s open to the idea of a Pink Floyd hologram show, à la ABBA Voyage, but only under a “series of very, very difficult and onerous conditions.”

The comments came in a new interview with Uncut, ahead of Gilmour’s first new album in nearly a decade, Luck and Strange (due on September 6th). Revealing that he and his wife, Polly Samson, had been invited to watch the ABBA Voyage show, the guitarist explained that he wasn’t quite blown away with the visuals of the hologram format, but appreciated the music.

“If you were a determined ABBA fan, you might enjoy it,” he said (per NME). “I thought the images of them were sort of OK, but they weren’t ever going to convince me it was real. If you’re down the sort of mosh pit end of the thing and it’s all going on, it’s probably great. The best moment for me was when the live band played a song [‘Does Your Mother Know’] on their own.”

Then, when asked what he would think of a Pink Floyd hologram show, Gilmour approved of the idea, but not without caveats. “If someone came up with all the money and all the brilliant ideas – and then once we’ve agreed to a series of very, very difficult and onerous conditions – I’d say, ‘Yeah, OK.’”

It’s unclear exactly what those “very, very difficult” would be, but considering some of the tensions among Pink Floyd’s former members, we can take a few guesses.

If it’s the “they weren’t ever going to convince me it was real” visuals that Gilmour is concerned with, though, perhaps things are looking up. The Swedish entertainment and music investment firm Pophouse, who played a role in creating the ABBA Voyage show, recently acquired the IP of KISS to produce a new show, and will invest “about $200 million to take it to the next level,” according to the band’s Gene Simmons.

In other Gilmour news, Luck and Strange is out on September 6th via Sony Music. Last week, the album’s first single arrived: “The Piper’s Call,” with music by Gilmour and lyrics by his wife, Samson.
