Cold Blood is an American R&B band that first gained prominence in the late 1960s and early 1970s. Known for their unique fusion of funk, soul, and jazz, the band is often associated with the Bay Area psychedelic movement. The group is particularly noted for the powerhouse vocals of Lydia Pense, often compared to that of Janis Joplin. Their self-titled debut album "Cold Blood" and their hit single "You Got Me Hummin'" have left a significant mark on the R&B and funk music scene.
