Three MTA Arts & Design artists have come together in an exhibition focusing on issues of identity and culture, community activism and peaceful co-existence. Curated by Nitza Tufino (her work can be seen at 86th Stand103rd St in Manhattan), “Essentia” opens at Taller Boricua Gallery Friday night, 1/22, 6:30-8:30pm. The show includes artists Robin Holder, whose vivacious “Migration”(2006) is installed at the Flushing Avenue station and Maria Dominguez whose energetic “El Views” (2002) is located at Chauncey Street station.
