Originally named "Superior Concept Monsters", the group was incorporated as a non-profit in 2005 and renamed Processional Arts Workshop with a mission to create site-specific community-built processions, parades, and other open-space performances.
These works are often developed through open community workshops that bring hundreds of volunteers together to build, rehearse, and ultimately perform cyclical pieces specifically for the parade.
In 2006, Kahn was awarded a Fulbright Scholarship to Trinidad and Tobago, to study the artistic and cultural structures behind Caribbean Carnival and Trinidadian "Mas'", or costumed procession.
During this time he created lighting, objects, and effects for performance artists including John Jesurun ("Chang in a Void Moon"), Mikel Rouse ("Failing Kansas"), Roseanne Spradlin, Meredith Monk, Pauline Oliveros, and David Hykes.
San Francisco Chronicle art critic Kenneth Baker described the work as follows: In a dark box several objects, including a broken fluorescent tube and a floppy disk, glow with touches of color under ultraviolet light.
