Briggs's music first appeared in a 1989 MicroProse release Sword of the Samurai. Following that, most MicroProse games featured his work. Before working in software entertainment, Briggs' music had already received performances by ensembles internationally in Paris' Pompidou Centre ("Ecliptic"), New York City's Avery Fisher Hall ("Comets"), and in the Krannert Center for the Performing Arts in Illinois ("Adjectives," "Firaxis", "Chimera," "Aurora," and others) as well as various smaller venues in New York and other cities throughout the United States. In 1996, he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
