A major influence on Reed's recording was the mid-1960s drone music work of La Monte Young's Theater of Eternal Music.

The entire album is made up of guitar feedback played at different speeds.

As a radical departure from the rest of Reed's catalog, Metal Machine Music is generally considered to be either a joke, a grudging fulfillment of a contractual obligation, or an early example of noise music. The album features no songs or even recognizably structured compositions, eschewing melody and rhythm for an hour of over-modulated feedback and guitar effects, intricately mixed at varying speeds by Reed himself.
