One-man band

A one-man band is a musician who plays a number of instruments simultaneously using their hands, feet, limbs, and various mechanical or electronic contraptions. One-man bands also often sing while they perform. The simplest type of "one-man band" is a singer accompanying themselves on acoustic guitar and playing a harmonica mounted in a metal "harp rack" below the mouth. This approach is often taken by buskers and folk music singer-guitarists.
