Primus's lack of cachet perhaps explains the existence of their new best-of CD, They Can't All Be Zingers. Indeed, the Zingers cover sarcastically admits as much: "Classic Primus songs repackaged for your listening convenience and our financial benefit." Though Zingers does manage to compile the band's best songs, more or less, the need for it is unclear, since Primus's career has been defined not by singles, but by albums. And what albums they are. The first five Primus records, built on the high-flying joy of unrestrained musical imagination, are a carnival of boredom and adventure, frustration and laughter, drugs, sex, war, death, NASCAR and fishing -- in short, the great driving forces of American rock. The lineup that made those records has been reunited recently, and Primus is again as we all should be: free to be wankers, and proud to be dorks.
