Curated by the Mexico City gallery Proyectos Monclova in a swap with Berlin’s Tanya Leighton Gallery, the opening of “ASIATACO” suggested a Mariachi-flavored Friday-night block party, with the artists playing the role of service industry operatives. Simon Fujiwara and his cousins lined up like a fast-food employees,  serving hundreds of homemade Japanese-Mexican fusion tacos that tasted like an experimental East L.A. taco truck had been beamed in. Neukölln’s hybrid bar/off-space Times Bar run by artists Calla Henkel, Lindsay Lawson and Max Pitegoff produced vicious margaritas that stripped away reservations and inaugurated a temporary dance floor. The on-view works by Calla Henkel and Max Pitegoff, Christian Jankowski, Eduardo Sarabia and Simon Fujiwara, too, pile up the  ambience of long distance exchanges and the microeconomics attached. Fujiwara’s Dir America (2011) reads like a account of the time he dictated a letter in English to a monolingual Mexican scribe. While for Künstlerfade (Ugly Sculptures) (2010), Jankowski memorialized a disposable napkin turned hand-drawn map by reproducing it as a wool carpet. Set in a site of business trade-offs, this summertime exhibition deliciously connects a smorgasbord of transaction-heavy exchanges with breezy rigor. This show deserves its 8th place in our top 10, not only thanks to the quality of the artists presented and the nice idea of exchange with a foreign gallery, but also because we particularly appreciated the use of the opening as event and performance.
