Robert Plant's perpetual musical restlessness is one of the reasons why his solo career has been so fascinating, particularly in recent years. It seems that his next stop might be towards the world of electronic dance music (EDM), with Diplo as his personal guide.

According to Consequence of Sound, the popular DJ-producer posted a selfie of the two of them to his Instagram account over the weekend, complete with the message "Collab coming soon." Sadly, that's all the details we have for you right now.

Plant, meanwhile, has a busy schedule ahead of him. He's got a four-song live EP, More Roar, coming up for Record Store Day on April 18. A week later, he'll perform at the Kennedy Center with Alison Krauss as part of a tribute to Lead Belly. Then, in late May, he will embark on a three-week tour of North American tour that will include a slot at the closing night of Bonnaroo on June 14.

Diplo, whose real name is Thomas Wesley Pentz, is currently one of the most in-demand producers in EDM right now. Over the past five years, he's produced or remixed songs by such big names as Justin Bieber, Madonna, Bruno Mars, M.I.A., Chris Brown, Beyonce and Usher. He was nominated for a Grammy for Best Non-Classical Producer in 2013.
