Norwegian progsters Leprous are back in the studio working on the follow-up album to 2013's Coal, which was successfully promoted with tours through Europe, Japan, North America and The UK. The still-untitled new album is due for a May 2015 release via InsideOutMusic.

Leprous has checked in with the following update straight from the studio: "We're super-stoked about the new material we have composed. It's not really Coal material, following our mantra about not making the same album twice.

The writing process has been very different this time. Most of the music has been made by Einar, on a computer. Almost all the guitar riffs for example (and Einar has no idea about how to play guitar), so the guitar players were up for a challenge.

At the moment we've finished recording drums, and Baard has delivered a stunning performance, so now it's time for the rest of us, to lay down the guitars, bass and keys, before we round the whole thing up with vocal recordings in the beginning of the new year.

Mixing and mastering will take place in late January, so we expect a release in May, but all of that is up to our label. Right now, we're just concentrating on doing our part to perfection."

Leprous has recorded the drums for their new album in Sweden's Fascination Street / Studio Gröndal with David Castillo (Katatonia, Opeth) and will - just like on Coal and its preceding album Bilateral - be mixing the album with Jens Bogren at Fascination Street Studio.
