The band commented: "We are very honored to join the Candlelight roster. To be included among such talented artists is very humbling, and we thank the great people at Candlelight for giving us the opportunity."
Metal Hammer called Demon Lung's four-song demo, Pareidolia, "earthy yet horror-themed doom Metal a la Candlemass with an Acrimony groove." The magazine called Fredrick a "wild-eyed, satanic songstress." Popular music and film site Ave Noctum noted, "Demon Lung has a deft touch and solid sound. Their Music is clearly from the Soul. Fair to say they are a welcomed addition to the ranks of the doomed." Teeth Of The Divine added, "Fredrick has the requisite sultry pipes that keep a steady, hazy tone. She has a deep, bluesy voice that fits the languid music perfectly."
Demon Lung has performed alongside Pentagram, High On Fire, Jucifer, Witch Mountain and Castle and will resume performing once recording has been completed.
