Contemporary Art Underground presents more than 100 permanent projects completed between 2015 and 2023 by MTA Arts & Design. This ground-breaking program of site-specific projects by a broad spectrum of well-known and emerging contemporary artists has helped to create a sense of character and place at subway and commuter rail stations throughout the MTA system. Among the featured artists are Yayoi Kusama, Kiki Smith, Nick Cave, Ann Hamilton, Xenobia Bailey, Jim Hodges, Alex Katz, Sarah Sze, and Vik Muniz. Of special interest is the discussion of fabricating and transposing the artist's rendering or model into mosaic, glass, or metal, the materials that can survive in the transit environment. This is the definitive survey of the latest works of the internationally acclaimed MTA Arts & Design collection. On view 24 hours a day, the collection is seen by more than four million subway riders and commuters daily and has been hailed as 'New York's Underground Art Museum.' The collection enlivens stations in all boroughs, with a myriad works by major contemporary artists executed in mosaic, glass, metal, and ceramic.
