[2] The band's second EP Bone Kingdom, released in February 2012 was the first to carry a deathcore sound, albeit in a more progressive style.

Lorna Shore followed the release of Maleficium by opening Carnifex's Die Without Hope Tour featuring I Declare War, Betraying the Martyrs and Here Comes the Kraken.

[5] Since then, before releasing their debut album they have toured with acts such as The Black Dahlia Murder,[6] Within the Ruins,[7] Archspire,[8][9] Oceano,[10] Fallujah,[8][9] Fit for an Autopsy,[11] Rivers of Nihil,[11][12] Cattle Decapitation,[12] Upon a Burning Body,[13] The Last Ten Seconds of Life,[10] and Chelsea Grin.

[18][19] The album was produced by Carson Slovak and Grant McFarland at Atrium Audio, who are known for working alongside bands such as August Burns Red and From Ashes to New, among others.

[22] In early 2017, bassist Gary Herrera announced his departure due to him losing interest in making music.

[3] After McCreery joined Lorna Shore, the band released two singles, titled "This Is Hell" and "Darkest Spawn".

[33] Despite the situation, Lorna Shore went on to tour Europe in support of Immortal, recruiting vocalist Will Ramos (formerly of Monument of a Memory and A Wake in Providence) as a stand-in.

Ricky Aarons writing for Wall of Sound reviewed the EP and title track stating: "The band continue with the epic vehicle of destruction, but change tact slightly, in a way that's reminiscent of their previous work...

Instead of the song focusing on breakdown ferocity it's more about stead-fast blast beats and the technical element of this wonderful band.

"[41] On April 29, 2022, the band debuted a new song, "Sun//Eater", during a concert from their upcoming full length album, titled Pain Remains.

[42] As well as the album announcement, the new single was the first to feature new bassist Michael Yager, who joined the band during the recording sessions for Pain Remains.

On June 22, Lorna Shore debuted their second single from their upcoming album titled "Into the Earth" with an accompanying music video.

[59] The band's early work showed one-time experiments in other metal genres outside their primary sound; their debut EP Triumph has been described as metalcore, their second EP Bone Kingdom moved into a progressive deathcore sound,[2] their third EP Maleficium was the first to show influences from black metal, and their debut album Psalms is referred to as more of a technical death metal album with the breakdowns expected in deathcore.
