Nox Aeris is the second major label studio album and fifth overall by rock band Janus. The album was released on March 27, 2012.[1] The song "Stains" peaked at No.26 on the Billboard Mainstream Rock Chart.
The album title is Latin for "night air" and stems from the Black Death-era belief that going outdoors at night made people susceptible to the disease.[2] Two slightly different album covers were released, depicting a person with a plague mask.
