The Night Demon EP was well received by the underground heavy metal press; According to a Blabbermouth.net review, the tracks would appeal to existing fans of vintage headbanger music and also attract some new listeners to the genre.

Night Demon's full-length debut album, Curse of the Damned, was released in January 2015 on SPV in Europe and on Century Media Records in the rest of the world.

Night Demon's second album, Darkness Remains, was released in April 2017 on SPV in Europe and on Century Media Records in the rest of the world.

Darkness Remains was released to positive reviews from the worldwide heavy metal press, including monthly soundcheck rankings of #1 in Deaf Forever magazine and #3 in Hard Rock.

The German Metal Hammer magazine praised Darkness Remains and recommended the album to fans of early music by Iron Maiden, Jaguar, and Tygers of Pan Tang.

On November 30, 2018, the band performed at the Decibel Magazine festival pre-party at the legendary Troubadour nightclub in West Hollywood, California, supporting Armored Saint.

[22] On February 2–3, 2019, Night Demon played a pair of shows aboard the Independence of the Seas cruise ship as part of the 70000 Tons of Metal Festival traveling between Ft. Lauderdale and Haiti.

Entitled Outsider, the album tells the story of a young gravedigger named Johnny who inadvertently stumbles into an alternate, shadow realm of his own hometown through a mysterious green mist that encircles the town.

One reviewer wrote, "Given the passion on display for the glory days, however, methinks Night Demon are on course to creating the best version of it they possibly can; if you literally need heavy metal to live, then Outsider might be immortality on tap.

It's a no-fuss, no-mess motorcycle ride along the highway of heavy metal history, blaring anthemic earworms and fist-pumping choruses all the way down.

While that highway might be a straight and fairly unchallenging one, Night Demon have still captured and recreated that sensation of past metal glories as close to truly as possible while implementing their personal touches.

[34] In addition to return engagements throughout Europe, the band's Outsider touring itinerary has brought them to previously-unseen territories such as Japan, Australia and even China, with many of those dates also featuring fellow Ventura metallurgists Cirith Ungol.

In spring 2024, Night Demon embarked on a full-scale North American tour in direct support of German heavy metal legends Blind Guardian.

[35] Along with Overkill, Night Demon will support King Diamond on their Saint Lucifer's Hospital 1920 tour in North America from October to December 2024.
