Newgrass is a genre of music that blends traditional bluegrass with elements from other styles, such as rock, jazz, and folk. It emerged in the 1970s, characterized by its use of electric instruments and innovative arrangements, which set it apart from classic bluegrass. Artists like Sam Bush and The Infamous Stringdusters are known for their contributions to newgrass, often incorporating improvisation and diverse musical influences. This genre appeals to a wide audience, as it maintains the acoustic roots of bluegrass while exploring new sounds and rhythms.
