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

Comparisons were also made between vocalist Chris Shinn and Shannon Hoon, due to their similar vocal styles and lyrical content, though Allmusic writer Greg Prato believes Shinn has "brought a more modern rock sound to the proceedings."

The lineup consisted of Chris Shinn (lead vocals, rhythm guitar), formerly of Celia Green, former Blind Melon members Christopher Thorn (lead guitar) and Brad Smith (bass) as well as Dave Krusen (drums) formerly of Pearl
