Through a complex research-oriented practice, Allora & Calzadilla critically address the intersections and complicities between the cultural, the historical and the geopolitical. The interdisciplinary nature of their interventions is echoed by an expanded use of the artistic medium that includes performance, sculpture, sound, video and photography. Their dynamic engagement with the art historical results in an acute attention to both the conceptual and the material, the metaphoric as well as the literal. The Puerto Rico-based artists have studied the ephemeral nature of collective drawing with monumental sticks of chalk at the Biennial de Lima, Peru (Chalk [Lima], 1998–2002); the imprints of colonial, nationalist, and military violence on the diverse populations and landscapes of Vieques, Puerto Rico (Land Mark (Foot Prints), 2001–2002; Land Mark, 2003; Returning a Sound, 2004; Under Discussion, 2006 and Half Mast/Full Mast, 2011); and the resonance of playing, warping and combining music from various moments in history (Clamor, 2006; Wake Up, 2007; Sediments Sentiments- Figures of Speech, 2008; Stop, Repair, Prepare: Variations on Ode to Joy for a Prepared Piano, 2008; Raptor’s Rapture, 2012; Apotomē, 2013; 3, 2013); as well as the entanglement between biophysics, semiotics and actuality (Growth, 2004; Puerto Rican Light - Cueva Vientos, 2015).
