Nicolas Bouvier is Sparth.
He has been an art director and concept designer in the gaming industry since 1996. Born in France, he now lives in Dallas, TEXAS, working for IDsoftware.
Included in the book are concept art and matte paintings from his impressive portfolio. Some projects he has worked on includes Alone in the Dark (2001), Prince of Persia - Warrior Within (2004), Cold Fear (2005), and Assassin's Creed (2007). Art for Alone in the Dark and Cold Fear are not included.
The theme for his art is primarily futuristic science fiction and space. There are quite a few cityscape paintings with flying ships. The worlds he created as just as imaginative as Star Wars. There's no caption on the art except for the titles and dates.
This book is recommended especially to science fiction concept artists.
Sparth has a website for the book, as well as a blog. You can find additional paintings in his art galleries.
