A minor, if reasonably interesting, late-'60s psychedelic group, Houston's Fever Tree is most famous for their single "San Francisco Girls," with its dramatic melody, utopian lyrics, and searing fuzz guitar. Most of their best material, ironically, was written by their over-30 husband-wife production team, Scott and Vivian Holtzman, who had previously written material for Tex Ritter and the Mary Poppins soundtrack. These odd bedfellows produced some fairly distinctive material with more classical/Baroque influences and orchestral string arrangements than were usually found in psychedelic groups. Their pretty, wistful ballads (enhanced on their first album by arranger David Angel, who had also worked on Love's classic Forever Changes) endure better than their dirge-like fuzz grinders, which epitomize some of the more generic aspects of heavy psychedelia. Releasing four albums (the third of which, Creation, included guest guitar by future ZZ Top axeman Billy Gibbons), their records grew weaker and more meandering with time, and the group disbanded in 1970. ~ Richie Unterberger
