On June 27, 2022, Nav took to Twitter to announce the title of the album and shared a screenshot of the tweet on social media.[1] On July 29, 2022, he released the lead single, "Never Sleep", a collaboration with American rapper Lil Baby, which features fellow American rapper and singer Travis Scott.[2] The same day the song was released, he was interviewed by Complex, in which he spoke about the album and how it was named:
The album title was inspired by a sweater that my friend had made. And I've begged him to get the sweater. I was like, "Yo, I wanna wear your shit and support my friend's stuff." So he brought it out and it had that on the back of the sweater. And it was very meaningful to me, because he came up with that himself when his mom passed away about a year ago. So I was like, "Wow, that's even better." Like, it actually has a good meeting [sic]. So that's why we came up with it. [...] Someone close to me had pointed my eyes toward the sweater. They're like, "Oh, that's fire, can you make an album called that?" But the whole quote on this sweater was "fighting demons protected by angels." We thought it was too long. Then one of my producers had mentioned, "Maybe we should take the 'fighting' out." We thought about it, and called our friends to ask them their opinion. We all said it's kind of dope. Then one day we were playing dominoes in the studio, and I just randomly asked him, 'How'd you come up with that?' He found that on Google, and then he told me where it's from. It was even more meaningful.[3]
On August 23, 2022, Nav released the second single of the album, "Wrong Decisions".[4] Exactly one week later, he revealed the release date, along with a trailer video that revealed the guest artists, which did not include American rapper Gunna on the list at the time.[5] On September 5, 2022, Nav shared the cover art for the album.[6] He revealed the tracklist in collaboration with Spotifyhip hop playlist RapCaviar the following day.[7] On September 8, 2022, the day before the album was released, Nav was interviewed by Canadian-American YouTube channel Nelk's Full Send Podcast, in which he revealed that he recorded a song with fellow Canadian rapper and singer Drake, but he decided to not include it on the album because he felt that they "could've done a better song and the timeframe was just not good" and along with the latter is "such a big artist" that he did not want the song to "take away from anything else on the album".[8] On September 13, 2022, "One Time", a collaboration with American rapper and singer Don Toliver, which features fellow American rapper Future, was released as the third and final single of the album.[9]
Demons Protected by Angels was met with generally mixed reviews. At Metacritic, which assigns a normalized rating out of 100 to reviews from professional publications, the album received an average score of 59 based on 4 reviews, indicating "mixed or average reviews".[10] Writing for Pitchfork, Matthew Ritchie felt that Nav "attempts to shift focus away from the beats and features, finally treating the songs like they're his own" and "Nav lets extended moments of true self-awareness break through his manicured shell, momentarily deviating from the soulless bars that often fill his albums", but conversely added that "ceding too much room to guests undermines Nav's individuality and causes the star-powered tracks to veer toward the generic".[12]
Demons Protected by Angels debuted at number two on the US Billboard 200 chart, earning 67,000 album-equivalent units, of which 26,000 were in pure album sales in its first week.[15] It serves as Nav's fifth consecutive top-ten album in the country.[16] The album also accumulated a total of 60.13 million on-demand streams of the album's songs during the tracking week.[17]
