Fire Make Thunder is the fourth studio album by American progressive rock band OSI, released by Metal Blade Records on March 27, 2012 in Europe and North America.

As with the previous albums, both Jim Matheos and Kevin Moore wrote and recorded alone and sent song ideas back and forth for further elaboration.

In May 2010 Metal Blade announced they had signed OSI and that guitarist Jim Matheos and keyboardist/vocalist Kevin Moore were currently working on the fourth album originally slated for a late 2010 release.

[6] Moore also stated that the album has a mood of consistency, better production and is more organic and unified than any previous release.

Moreover, he states that once he records a general melody he will begin to play back the material to develop accents and phrasing to match the music.

[9][10][11] Moore said it was something "always on our minds" and discussed the idea of performing a live studio version before embarking on any larger scale tours.

[13] Ken McGrath of Blistering gave the album 7 out of 10, stating that it "may require a little work initially from the listener", but called it a "real charmer of an album" consisting of "sepia-toned memory spiral", "big, fuzzy guitar chorus [riffs]" and "shimmering notes as if water dripping down glass".

[15] Bloody Disgusting's Jonathan Barkan defined the album as "a sonic journey where new and amazing tones and sounds assault you from all sides constantly" noting "something very industrial … not referring to the electronic subgenre" but a vision of "steel factories … grimy smokestacks rising up, a dark smog cloud hanging overhead … it sounds fantastic".
