What is "uncanny valley"

n. A range of appearances, mannerisms, and/or behaviors subtly different from humanoid in an otherwise humanoid figure that may cause negative reactions, such as fear, discomfort, or revulsion.

In aesthetics the uncanny valley is the hypothesis that human replicas that appear almost but not exactly like real human beings elicits feelings of eeriness and revulsion among some observers. Valley denotes a dip in the human observer's affinity for the replica, a relation that otherwise increases with the replica's human likeness. Examples can be found in robotics and 3D computer animation among others.

Uncanny Valley is the second full-length album by the Raleigh, NC-based rock band Birds of Avalon. The album was released by Volcom Entertainment on June 23, 2009.

Uncanny Valley is the third album from Australian electronic band Midnight Juggernauts. It was released on 14 June 2013 in Australia, and on later dates in June/July 2013 in other countries.

After their previous tour, the band took a few years break where they returned to focus on various experimental audio-visual projects. Eventually they started writing/recording sessions in a converted church in the French Loire Valley. They next released a music video anonymously, hidden under the guise of a Soviet pop band from the early 1980s. This Russian shot video unattributed to Midnight Juggernauts remained under this secret pretense for many weeks. When it was eventually recognised as a new Midnight Juggernauts track, it was then announced as , and their album Uncanny Valley was released soon after in mid-2013.

Their hybrid video for Memorium was also notable for its imaginative approach. Premiered on The Creators Project it revealed the pioneer history of CGI, and gained much attention amongst the Computer Graphic/Technology communities.

The band toured behind the release with Tame Impala before starting their own album launch tours across the globe.
