Hasil Adkins was an American singer-songwriter and multi-instrumentalist. His genres include rock and roll, country, blues and more commonly rockabilly, and because of his unusual playing and singing style, he is often cited as an example of outsider music. He generally performed as a one-man band, playing guitar and drums at the same time.

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.
