When writing lyrics for the album, frontman Rou Reynolds researched the topics he addressed, such as climate change and the global financial crisis, to make sure he was making accurate statements.
When choosing "which of the tracks they've been working on should make it on to ", Enter Shikari found it hard to decide. Therefore, they made a graph where "the vertical axis charted the heaviness of the songs  the horizontal one  their location on a scale ranging from 'accessible' to 'experimental'", and "where clusters indicated several songs covering the same territory, only one was allowed to make the cut", so that the album would feature something "from everywhere within  spectrum of sounds."
The Mindsweep has been described as a post-hardcore album which contains elements of many of genres including experimental rock, punk rock, dubstep, drum and bass, electronic rock, mathcore, alternative rock, alternative metal, british hip-hop, neoclassical, trip hop and many others.
Kerrang! Magazine called The Mindsweep the band's "most diverse album to date", contrasting the "punk thrash" of "There's a Price on Your Head" with "Dear Future Historians...", which they described as a "Radiohead-esque piano ballad". They also compared the style of "Anaesthetist" to that of the Prodigy.
