Cryoshell (often stylized as C R Y O S H E L L) is a Danish rock band from Copenhagen formed in 2006. The line-up consists of lead vocalist Christine Lorentzen, guitarist Kasper Søderlund and keyboardist Mikkel Maltha.

In the band's early years, they produced several songs that featured in promotional material for the Lego toy series Bionicle. In the wake of the line's 2010 discontinuation, they released their self-titled debut album. A sophomore effort, Next to Machines, is currently in production.

Cryoshell's musical style has been classified as alternative rock, hard rock and metal, and labelled similar to bands like Delain, Evanescence (both also fronted by a female singer), Linkin Park and Within Temptation.

The group that would later be called Cryoshell was formed in Copenhagen, Denmark in late 2006. Music composer Mikkel Maltha was commissioned by the Lego Group to produce a song to be used in the promotional campaign of a forthcoming release of Lego toys. Maltha wrote "Creeping in My Soul" with fellow composer Anthony Lledo and produced the track with Eddie Simonsen and musician Kasper Søderlund. Vocals were provided by Christine Lorentzen – a former TV presenter and employee of the creative agency Advance – after she auditioned for the part.

"Creeping in My Soul" featured in commercials, online games and other media advertising Lego's Bionicle Barraki wave in 2007. When the song was released as free MP3 download, it became the number-one most downloaded file from the official Lego website and reached over one million views across various videos encompassing the song on YouTube. Riding on this success, Maltha, Søderlund and Simonsen went on to produce "Face Me" and "Gravity Hurts" with established Danish singer Niels Brinck for the campaigns of Bionicle's 2007 Mahri and 2008 Phantoka waves, respectively.

Lorentzen rejoined Maltha and Søderlund to record "Closer to the Truth" for Bionicle's Mistika wave in 2008. The song served as the group's first official release under the band name Cryoshell. Plans to record a full-length album for a late 2008 release were announced, but production was pushed back to the following year.

Cryoshell spent the majority of 2009 recording their self-titled debut album with producer Jacob Hansen. The lead single "Bye Bye Babylon" was released in July 2009, simultaneously serving as the band's fifth and final song used by Bionicle; this time for their Glatorian and Glatorian Legends waves. A re-recorded version of "Creeping in My Soul" was released as the second single in November, followed by an EP baring the same name in January 2010. Cryoshell was released on June 7, 2010 solely in Scandinavia due to difficulties in securing an international distribution but slowly became available overseas over the next few years.

Lorentzen took maternity leave from the band between November 2011–October 2013. In her place, Tine Midtgaard, a runner-up on the 2010 series of the Danish incarnation of the talent show The X Factor, provided vocals for two new recordings – "Breakout" and a remix of "Gravity Hurts" – the former of which received a single release in December 2012. When Lorentzen rejoined, it was stated that both songs would be included as bonus tracks on an international reissue of Cryoshell's debut album under Greek record label The Leaders. However, a release date was never announced and the plans are thought to have been scrapped.

In February 2015, concept artist Christian Faber confirmed that Cryoshell would produce the soundtrack for Rebel Nature, a multimedia project that he is currently developing. Recording began the following September for a mobile app game called Escape RIG21.^[1]

Songs inspired by Rebel Nature will make up Cryoshell's second studio album Next to Machines. Production was originally going to be crowdfunded via Kickstarter, however, the band managed to secure their own finance prior to the campaign's May 2017 launch.^[2] Four singles were released ahead of the album in 2018 – an orchestral remix of "Gravity Hurts" with Lorentzen and the Budapest Art Orchestra, "Nature Girl" (a cover of "Nature Boy" by Nat King Cole), "Don't Look Down" and "Slipping". The "Gravity Hurts" mixes featuring Brinck and Midgaard also received singular releases in December 2018.

Cryoshell have released 1 studio album, 1 extended play, 9 singles and 6 music videos.
