Part of the commonwealth series, a set of five interstial castings comissioned by Buffalo Arts Studio to document the social, physical, and emotional support provided by local health and human service organizations like Aspire WNY, Inc. iXpress, Cantalician/Diversified Labor Solutions, and the Buffalo Arts Studio Jump Start program. Interstitial Castings are negative space castings of people engaged in choreographies of the intimate. They are the space between two people enacting their relationship through gesture. The Buffalo Art Studios commission was an opportunity to investigate different communication strategies and reassess choreographies of the intimate that are often taken for granted like those of care and labor. Bolster is the interstitial space between the Buffalo Arts Studio Jump Start administrator and a participant in the Jump Start program. It is the negative space between him showing her art work on his cell phone.
