One of the most dexterous soundtracks to emerge from the Nintendo assembly line in recent memory is none other than this rich, versatile offering from veteran Koji Kondo and relative newcomer Mahito Yokota. The sweeping display of orchestrated opulence is reminiscent of past Mario titles complimented with a sometimes organic feel (reminiscent of Pikmin) with hints of John Williams' works on Star Wars (for much of the "imperial" motifs used for Bowser and his space legion), among several cosmic influences. It fits Super Mario Galaxy's mold perfectly, and does nothing less than enhance an already nearly-pristine gaming experience.
