Muse have been dropping further hints about their next album, which they have promised fans is going to be "heavy".

Frontman Matt Bellamy has been interacting with fans on Twitter - answering questions about their plans for the new LP.

One user asked him: "So, are you sticking to your 'going back to guitar/drums/bass' or was that just Matt being a tease?"

To which he replied: "yes. It's gonna get heavy."

And when another asked "How's the album coming along? You guys excited?" - Bellamy responded: "yes, going well. We hope to have it ready for next summer."

The band's last studio album was The 2nd Law from 2012, which went platinum.
