Over 30 years after Bam ditched the Black Spades gang and formed Zulu Nation (helping create hip-hop in the process), he’s back and showing the neo-electros how it’s done. You’ll have a hard time finding a better party album in 2004, especially one with Gary Numan on it. “Got That Vibe” cranks forward with a butter-smooth rap from King Komonzi, while Numan’s turn on “Metal” tosses you in a time machine and glues the door shut. The space funk of “2137” sounds like The Gap Band jumped R2D2 and started sequencing his innards. Careening confidently between Bollywood, salsa, African polyrhythms, jazz and Bam’s patented planet rock, Dark Matter should be mandatory listening for crunk suckers everywhere.
