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) to tour in support of their album. However, the tour was soon cancelled after Blind Melon parted ways with Warren. The band were to perform a number of shows with Thorn and Smith's former band mate Shinn, though a lack of preparation time resulted in the band cancelling the tour. Unified Theory released their second album "Cinematic" on iTunes in December 2006. The band did not reunite to perform any shows to promote the album. Unified Theory reunited for one show on August 4, 2010 at the King King in Hollywood. Chris Shinn's other band Everything is Energy opened the
