Fever Tree is the debut studio album by the American psychedelic rock band Fever Tree and was released on March 28, 1968 on Uni Records (see 1968 in music). It blended multiple influences ranging from psychedelia to baroque pop and folk rock, and was marked by eerie ballads and hard rock numbers. Much of the group's material was penned by the husband-wife songwriting duo of Scott and Vivian Holtzman, along with renditions of contemporary rock songs. The album was preceded by arguably Fever Tree's best known song, "San Francisco Girls (Return of the Native)", becoming the group's only nationally charting single. Like its attendant single, Fever Tree was also moderately successful and managed to reach number 156 on the Billboard 200.
