Wikipedia
Cryonics (from Greek κρύος 'kryos-' meaning 'cold') is the low-temperature preservation (usually at -196 °C) of people who cannot be sustained by contemporary medicine, with the hope that resuscitation and restoration to full health may be possible in the far future. Cryopreservation of humans is not reversible with present technology; cryonicists hope that medical advances will someday allow cryopreserved people to be revived.
Cryonics is regarded with skepticism within the mainstream scientific community and is not part of normal medical practice. It is not known if it will ever be possible to revive a cryopreserved human being. Cryonics depends on beliefs that death is a process rather than an event, clinical death is a prognosis of death rather than a diagnosis of death, and that the cryonics patient has not experienced information-theoretic death. Such views are at the speculative edge of medicine.
Cryonics procedures can only begin after legal death, and cryonics "patients" are considered legally dead. Cryonics procedures ideally begin within minutes of cardiac arrest, and use cryoprotectants to prevent ice formation during cryopreservation. The first human being to be cryopreserved was Dr. James Bedford in 1967. As of 2014, about 250 people were cryopreserved in the United States, with 1500 more having made arrangements for cryopreservation after their legal death.
Cryonics is the first album released by the band Hot Cross on Level Plane, featuring a total of ten tracks. It was their first full-length album and follows their 2001 debut EP A New Set of Lungs.

Human cryonics is not an especially advanced science right now, and those who have themselves frozen rather than buried or cremated are unlikely ever to be revived (partly because current laws require that they be dead prior to freezing, but even if they weren't, the tremendous damage inflicted on human tissues in the freezing process means they'll be thawed out as cellular mush).
