Tom Lavazzi’s ‘Let This Sentence Be Your Guide: Diagrammatic alterity and performative de(X)-touring of urban cityscapes,’ as hybrid performance and socio-cultural critique, is a pilot/trial run for group or individual actions that interrogate the limits of a schematic epistemology. Notwithstanding the site-specific orientation of the piece, it can serve as a template for historically-torqued reappropriations of commercialized appropriations of urbanscapes generally. The piece semi-arbitrarily overlays a tourist map of Savannah, GA, with a Reed-Kellogg formatted diagram of a tourist brochure’s place-branding sentence; the diagram is then deployed as an alternate ‘tour’ route, the nodes of the diagram corresponding to ‘stops’ on the tour. ‘Tourist’/performers are cast, or repositioned, as critically-conscious Situationist flâneurs, finding themselves at junctures which may or may not correspond to conventional tourist ‘sites’, hence dialogically deforming them, with the aid of virtual historical texts haptically accessed (i.e., via mobile devices) in real time, as sites for critical intervention. Given the Old South ideological mise en scène implied by the brochure’s branding rhetoric, and featured in many of the city’s ‘historical’ markers, the piece also detours an 18th century dance form, the quadrille, as imaginative leitmotif for the critical movement. Informed by Situationist flâneurisme, Actor Network Theory’s (ANT) materialist semiosis, letterist graphemic elaborations of language (between letter and graph, drawing and text), and antebellum ballroom etiquette, the piece imaginatively reconfigures and hence reconceives the branded cityscape. Once a sentence is diagrammed, and the words removed, the empty from of syntax as spatialized design becomes a path of the subject through ideologically sutured space; the words remain, however, a contested, shadow rhetoric hovering above their syntactic lineation. ‘Let This Sentence Be Your Guide’ is the textual trace/reenactment – re-composition – of a literal walking (imaginative ‘dancing’ –diachronic/dialogic writing through--) the lines …
