If you like Primus, I have to recommend that you check out some of Les Claypool's other projects like The Holy Mackerel, The Frog Brigade, and Oysterhead (with Phish's Trey Anastasio and The Police's Stewart Copeland). Even better, try to see him live. I did so earlier this year and it was quite an experience.
Before closing, I must comment on the packaging. It is a clever plastic wrap designed to look like a package of individually packaged cheese slices, right down to the way the label is shown. I like it, but I also don't like it. They did a similar thing on The Brown Album, the songs are on the wrapper, so when you rip it off, you are left with a jewel case that looks like cheese with no information or track listing. I would at least like to have the track listing on the back.
Bottom line. This is a great summary of Primus, an illustrious band which Claypool says "was never supposed to accomplish the kind of things we accomplished." They have definitely left a mark, and continue to leave one on the music world. A collection like this usually marks the end of a band, but something tells me we have not heard the last of Primus. Get this album, whether you are an old fan, or one of the curious, it is well worth the money and the time to listen.
