British prog-rockers Muse have posted a sneaky album rehearsal video on Instagram, featuring orchestral studio sessions recorded for their forthcoming album.

The trio are currently working on their highly-anticipated, seventh studio album, which is due to be released at some point in 2015. The bombastic band, who are among the favourites to headline Glastonbury in 2015, are recording the follow-up to their sixth album The 2nd Law, which was released in 2012 and toured globally in 2013.

Answering fan questions on Twitter back in September, frontman Matt Bellamy said that he might have to contradict comments he made about guitar solos in the past while also stating that the themes of the new material include “Deep ecology, the empathy gap and world war 3”. Additionally, it was suggested that a “sequel” to Origin of Symmetry song ‘Citizen Erased’ could also feature on the new album.

Meanwhile, it was recently confirmed that Bellamy had split from his partner, actress Kate Hudson. The couple have been an item for four years and have a three-year-old son, Bingham.
