Muse are hard at work on their sixth studio album and are sharing the progress they've made so far. The U.K. rockers tweeted some photos of their current recording session and it seems like things are going according to plan.

Judging by the snapshots, the new record is destined to be just as ambitious as the trio's 2009 album 'The Resistance.' The photo above portrays Muse and musicians who have added "some strings" to the upcoming disc. The group also revealed on their Twitter page that they are working with a horn section.

According to NME, one of the photos is of Muse frontman Matt Bellamy collaborating with composer David Campbell on an orchestral score. Campbell has previously worked with Radiohead on '15 Steps,' U2's Broadway production 'Spiderman: Turn Off The Dark,' Beck's melancholic 'Sea Change' album and the Mars Volta.

The as-yet-untitled album is slated for an October 2012 release.
