"Citizen of Glass, the third album from Danish-born, Berlin-based singer-songwriter Agnes Obel, takes its title from the German concept of the gläserner bürger, meaning "the glass citizen." It's a legal term that refers to privacy — if somebody is glass, every detail about them is known. Though like the material itself, a person can, of course, never be totally transparent. Like glass, one can be distorted, cracked or even a reflection of something else. 
 
Obel uses this idea to create her most ambitious work to date, both conceptually and instrumentally. While 2010's Philharmonics and 2013's Aventine were applauded for the artist's piano work and the hushed beauty of her voice, here Obel complements her compositions with grandiose instrumentation, including violin, cello, spinet and the Trautonium. The additions are magnificent and never overwhelm, staying true to Obel's commitment to minimalism and forming a haunting, symphonic quality that partners with delicate vocals as they lead the way through the album." - Exclaim
