Throughout the 1960's, 1970's and 1980's electric guitars were prominent as the instrument of choice for many, many bands. Today, rock and alternative bands still make good use of the electric guitar, some noteable examples being Metallica, 3 Doors Down, Dave Matthews Band, and Aerosmith.

Usually accompanied by drums, a bass guitar (a deeper string sound), vocals, and occasionally an acoustic guitar, harmonica, or piano.
