This set compiles much of DJ Shadow's pre-major label material in one convenient package in an attempt to foil bootleggers and bring new fans up-to-date in the curriculum. The results are naturally varied, but all point to a marvellous evolution of talent. The collection is kept together primarily by its propensity for jazzy beats and psychedelic loops. Shadow (né Josh Davis) moves through everything from old school funk ("In/Flux") to grungy 1960s-style guitar rave-ups ("High Noon"). The centrepiece of the set, however, is a four-part composition called "What Does Your Soul Look Like", which is likely to be the first ever entirely sample-driven rock opera. It's a brilliant piece of work, laced with intriguing sounds, sound bites, and a detectable set of motion.
