Also similar to these groups is Sleepthief's use of pop music-based song structures with performances by female singers.

Born in Southern California, Elswick served as a missionary for the Church of Jesus Christ of Latter-day Saints in Texas and received a B.A.

Russell Elliot, editor-in-chief of Musical Discoveries, put Elswick in contact with singer Jody Quine[3] in December 2003.

[5][6][7] The lead single for the Labyrinthine Heart, "World Gone Crazy", features the vocals of Coury Palermo and was released as a digital download EP on June 30, 2009.

It was shot in the Goblin Valley State Park in Utah and features Jody Quine and Justin Curtis, Elswick himself in what can be defined a metaphor of the search for love.

[10] Jody Quine had a short insight on the song concept: "When Justin gave me the title 'Mortal Longing' and the ideas behind it I struggled with how to best embody it lyrically.

Choosing the right words that weren't cliche or cheesy can be difficult, but I think I found some very strong and vivid choices that portray the physical responses of being in love and also cry out for breath.

"Another new single, "This Means War", was recorded in June 2013 with Joanna Stevens and released as an EP on November 12, 2013, along with a science fiction-themed music video.
