The album's recording sessions were the first time Moore and Portnoy collaborated since 1994 in their work in Dream Theater.

Critics noted that the album was darker and more keyboard-focused than the band's debut. re:free, an EP featuring remixes of three tracks from Free, was released on October 24, 2006. The band were keen to tour in support of Free, but no live shows materialised. "The reality of it is in order to [tour] the way we would like... and present it the way we would want to present it... would cost too much money for the kind of fan base that we have right now," Matheos said in 2009. In 2010 he anticipated that OSI will "remain a studio band."

Matheos and Moore primarily work alone, exchanging files and ideas by email.

". The lyrics on Office of Strategic Influence feature political themes, but the lyrics on later releases are less political, instead being based on Moore's personal experiences. "I'll start writing a song that has a little bit of a world view or political view or something," he said, "but then by the time I'm finished the lyrics it'll be about a relationship or something like that." On Blood, Moore largely abandoned his earlier stream-of-consciousness approach to writing lyrics, in an attempt to make the lyrics more coherent. "I didn't want it to be like 'Oh, you get your own impression of the lyrics. Everybody has their own idea!' I wanted to have an idea that I wanted to communicate, and something communicable," he explained.

Moore has acknowledged the narrow range of his vocals. He considers his vocal style to "[come] from how I feel when I’m singing, when I'm in the zone of writing lyrics and recording which, a lot of times, comes as the same time. It's sort of an introspective time. A lot of the material lends itself to that kind of voice and that kind of spirit."
