Electric Blues is an eclectic genre that embraces just about every kind of blues that can be played on an amplified instrument. Its principal component is that of the electric guitar, but its amplified aspect can extend to the bass (usually a solid body Fender type model, but sometimes merely an old "slappin''' acoustic with a pickup attached), harmonica, and keyboard instruments. Stylistically, the form is a wide open field, accessible to just about every permutation possible -- embracing both the old, the new, and sometimes futuristic, and something that falls between the two. Some forms of it copy the older styles of urban blues (primarily the Chicago, Texas, and Louisiana variants) usually in a small combo format, while others head into funk and soul territory. Yet electric blues is elastic enough to include artists who pay homage to those vintage styles of playing while simultaneously recasting them in contemporary fashion. It is lastly a genre that provides a convenient umbrella for original artists of late '40s and early '50s derivation who seemingly resist neat classifications.
