On "Critical" and the "Critical Remix," Zion I are joined by Planet Asia. The original versions of "Critical" and "Venus" are produced by 418Hz. Madlib of Lootpack produced the remix of "Critical," which is real nice, the beat changing for each rapper's verse. There is also a remix of "Venus" with a very different drum'n'bass beat. The hyper drums of the remix work really well and don't disrupt the flow of Zion I. In 1999 there haven't been many combinations between hip-hop and drum'n'bass, but seeing how well this song works, it wouldn't be surprising to hear more in the future.
