Composite Truth is Mandrill's most successful album, commercially as well as artistically. Although the band's sense of freewheeling experimentation had been tempered, its gradual transition to a straight-ahead funk band was made perfect with two of the biggest hits of its career: "Hang Loose" and "Fencewalk." "Hang Loose" is all over the place (in a good way), moving from a grooving funk jam to mid-tempo guitar skronk and back, all part of an impassioned call to peace. "Fencewalk" also had several transitions, with a crooning chorus and an extended middle section powered by heavy brass and a screaming guitar solo.
One of funk's most progressive outfits, Mandrill paid the price for their ambitions in commercial returns not that they never earned a reputation or an audience, but their expansive, eclectic vision often worked better when given an album's worth of room to roam, rather than being condensed into hit singles. Mandrill's jam-heavy brand of funk was liberally infused with Latin, Caribbean, and jazz influences, plus blues, psychedelia, African music, and straight-up rock. Their freewheeling approach was a definite influence on the Parliament-Funkadelic collective (an early incarnation of which actually served as their opening act), and their grooves have been sampled by numerous hip-hop acts in modern days.
