The Lost Keys is a co-ed a cappella group based in New York City. From flashmob weddings to Rockwood Music Hall, this group has become a staple in the aca-music scene. 2015 marked the release of their debut EP, UNLOCKED. It was named one of the Top Albums of the Year by RARB, including two songs on the “Top songs of the year” list. Visit thelostkeysnyc.com for more information.

The evening will be hosted in a site-specific installation titled La Deliciosa Show, conceived by the artist Radamés “Juni” Figueroa as part of the High Line’s open-air group exhibition, Mutations, which looks at how boundaries between the natural world and culture are defined, crossed, and obliterated. You can learn more about the exhibition at art.thehighline.org.
