Christopher Weingarten’s 33 1/3 book on Public Enemy’s 1988 classic It Takes a Nation of Millions to Hold Us Back came out in April, but, for whatever reason, I didn’t finally pick it up until this past Saturday (the series could use more hip-hop titles, by the way).

Five days later, and DJ Z-Trip has released two remixes of Bring the Noise, a song from Nation of Millions that technically saw its first remix back in 1991 with the PE/Anthrax collaboration.

Z-Trip’s versions blend the original with Led Zeppelin’s Immigrant Song and Justice’s Genesis. Both are available for free download for the next 72 hours. Get ’em.
