The ECC arguably first infected the Net with the “mash-up” technique-still best heard on their classic 1993 “Whipped Cream Mix” of Chuck D rapping over a Herb Alpert big-band jaunt. Plagiarythm Nation is an assortment of their MP3 “hits” that sometimes proves that “copyright infringement is your best entertainment value,” as Negativland told us. “Rocked by Rape” stitches Dan Rather’s depressing headlines over an AC/DC riff, as if he’s crooning at a shit-kicker bar. Elsewhere, Janet Jackson and Gloria Estefan hits mutate into oddball ditties that resemble the Residents. Basically, this album is between-song, gag filler for late-night college radio.
