As the band is very environmentally conscious, The Fire... has a nature-driven theme with song titles such as "Last Day of Winter", "Autumn into Summer" and "Aurora Borealis".

With the exception of tracks like "March to the Sea" and "Red Ran Amber," The Fire... is also noted as deemphasizing the heaviness found on Australasia while significantly expanding the group's style in favor of complex, layered melody.

Many critics have expressed difficulty in labeling the album within a particular genre, but despite the range of influences involved in its creation, have often compared it to doom metal, post-rock, and groups like Isis.

Scott Alisoglu of Blabbermouth.net wrote, "The music of The Fire in our Throats... not only conjures visions of earth's explosive creation, but also the blending of pristine beauty with nature's unforgiving wrath.

"[citation needed] Andrew Bonazelli of Decibel, in reviewing Isis's 2004 Panopticon, compared the two albums and described their shared tone as "triumphant".
