Sonic Firestorm is the second studio album by British power metal band DragonForce, released through Noise Records on 11 May 2004. It is the first album to feature bassist Adrian Lambert and drummer Dave Mackintosh. The reissue of this album was released on 22 February 2010, along with a remixed and remastered version of the band's first album, Valley of the Damned. The re-release also came with the bonus track "Cry of the Brave", which was a Japanese bonus track on the original release.
The recording and mixing for the band's second album took place at Surrey's Thin Ice Studios, from 6 October to 10 December 2003. All the guitars were recorded at Herman Li's LamerLuser Studios in London.
Along with the bonus track "Cry of the Brave", which was initially only included as a Japanese bonus track on the original release, the 2010 re-release includes a bonus DVD with an interview from Dave Mackintosh and a commentary from Herman Li and Sam Totman, as well as live "Fury of the Storm" performance in Japan from 2005.
