Sakimoto originally heard of Ormond due to an arrangement he had made of "The Skycity of Bhujerba" in 2009, which, after discussion between the two about several other arrangements Ormond made of Sakimoto's work, lead to the two officially working together on "Valkyria Chronicles Piano Pieces", an album of piano arrangements for Valkyria Chronicles. The style of arrangements on the "Final Fantasy XII" album range from classical to a "moody piece with plenty of sultry jazz tones", one of the two pieces located at the end of the album which Ormond had arranged prior to officially beginning the project. Many of the pieces contain an "improvisational" sense, even when not technically jazz-based, and several depart notably from the style of the original works. Ormond based many of the changes in theme or mood of his arrangements off of where the pieces were used in the original game, attempting to highlight the perspectives of different characters or ideas from the scenes they were played in.
