Crystal World is the debut studio album by Scottish musician Marnie, self-released on 11 June 2013 through the site PledgeMusic.

Crystal World comprises ten original songs written by Marnie while Ladytron had a break after their fifth studio album, Gravity the Seducer in 2011.

"[1] On 24 May 2012, her Ladytron band-mate Daniel Hunt announced that he would produce Marnie's solo album in Iceland in August 2012.

I then wrote the final track 'Gold' at home in Glasgow late last year, flew for one last time to Reykjavík, and recorded it there in December 2012.

[8] Helen Marnie offered various items for potential pledgers, like digital download/CD/gatefold vinyl of the album, signed 8x10 studio photos, disposable cameras filled with random pictures chosen by her, market bags customized with her logo, screen printed posters, handwritten lyric sheets, a pair of shoes and a dress that she wore in Ladytron's "Tomorrow" music video, a blue bikini that she wore in a pool photoshoot, personalized ringtone package, test pressing package, and her 1998 Mini Cooper Sport car.

[8] On 29 May, Marnie premiered on her official YouTube account the music video for her debut single as solo artist, "The Hunter".

On 1 June, she shared to the pledgers a 55-second-long sample from a song titled "Hearts on Fire" and also confirmed the official track listing of the album.

[14] Marnie released a special single titled "The Hunter Remixed" through Les Disques du Crépuscule.

It was issued in a strictly limited edition of 500 copies on clear 12" vinyl to celebrate Record Store Day on 19 April 2014.

"[19] The music site The VPME rated Crystal World 10 out of 10 and named the album "an electro-pop map of the human heart with more empathy, warmth and spirit than a million contrived indie lad rock 'anthems'."

The reviewer also added: "make no mistake, this is a hugely emotive record which sees Helen step out from behind her mysterious sultry Ladytron persona and reveal herself to be a songwriter of enormous emotional depth and honesty, able to produce songs which are poetic, fragile, heartfelt and often downright heart-breakingly beautiful.

"[18] Victoria Segal on eMusic rated the album 4.5 out 5, saying that Crystal World "feels less strict, less pristine, as if all the wires and circuitry are slowly starting to melt down."
