Classical unified field theories describe the properties of the electromagnetic field as a purely geometric phenomenon. Einstein tried to form a generalized theory of gravitation that would unify the gravitational and electromagnetic forces (and perhaps others), guided by a belief in a single origin for the entire set of physical laws. These attempts initially concentrated on additional geometric notions such as vierbeins and "distant parallelism", but eventually centered around treating both the metric tensor and the affine connection as fundamental fields. (Because they are not independent, the metric-affine theory was somewhat complicated.) In general relativity, these fields are symmetric (in the matrix sense), but
Unified Theory (band) they relocated to Los Angeles and began recording their debut album. The album was recorded at Stank Face Laboratories and Lucky Dog Studios in Seattle, and was produced by both Thorn and Smith, and mixed by Andy Wallace. Jon Bolton and Matthew Steer contributed additional drums to the recording, while string arrangements were handled by Dave Dysart. In June, Unified Theory shot a music video for their first single "California" with director Bobby G, before touring the US in July. The band's debut album entitled "Unified Theory" was released on August 15, 2000, through 3.33 Music Group in North America
