My Grass is Blue 1977 Phone Case

Bluegrass is a genre of American roots music that developed in the 1940s in the Appalachian region of the United States. The genre derives its name from the band Bill Monroe and the Blue Grass Boys. Bluegrass features acoustic stringed instruments and emphasizes the off-beat. Notes are anticipated, in contrast to laid back blues where notes are behind the beat, which creates the higher energy characteristic of bluegrass. In bluegrass, as in some forms of jazz, one or more instruments each takes its turn playing the melody and improvising around it, while the others perform accompaniment; this is especially typified in tunes called breakdowns. This is in contrast to old-time music, in which all instruments play the melody together.
