Josh “DJ Shadow” Davis had already been experimenting with making beats and breaks on a four-track recorder while he was in high school in the Nor-Cal college town of Davis, but it was during university that he co-founded his own Solesides label as an outlet for his original tracks. Hooking up with Davis’ few b-boys (including eventual Solesides artists Blackalicious and Lyrics Born) through the college radio station, Shadow began releasing the Hip-Hop Reconstruction mix tapes in 1991, eventually catching the attention of The Source magazine and Dave Funkenklein. Shadow was featured in the magazine’s “Unsigned Hype” column in 1991, and Klein signed him to a production deal with Hollywood BASIC records. Concurrently, Shadow provided beats and scratches for Bay Area rapper Paris and was featured on his second album. In 1993, Shadow pressed his 17-minute beat-head symphony “Entropy.” His tracks spread widely through the DJ-strong hip-hop underground, eventually reaching James Lavelle of Mo’ Wax.
