Fever Tree was an American psychedelic rock band from Houston, Texas, that rose to prominence in the late 1960s. The band's musical style was characterized by its fusion of psychedelic rock with elements of pop, folk, and blues, and their signature sound was defined by the distinctive voice of lead vocalist Dennis Keller. Their most influential work, "San Francisco Girls (Return of the Native)", achieved chart success and is considered a classic of the psychedelic era. Despite disbanding in 1970, Fever Tree's contribution to the psychedelic rock genre has ensured their enduring significance in music history.
