On Gigantoid, the blond locks and tanned complexions that defined Fu Manchu in their early years are tempered by the hard-earned wrinkles and scars of passing years. The band wear their age well. Kevin Hill is much more convincing as a vocalist now that his voice has acquired some gruffness, and the band play with more experience and athleticism. “Dimension Shifter,” “Evolution Machine,” and “Radio Source Sagittarius” can easily hold their own against the hordes of newcomers that have only recently adopted the style Fu Manchu have been plying for 20 years.
