I like this album quite a bit. Primus definitely has a distinct sound. This album is different from anything I've ever heard. It has four of Primus' best songs and is excellent instrumental wise, IMO. It's definitely worth a listen, though it may not be for people who prefer more "serious" music. The lyrics are very out there.
My favorite songs, which also happen to be the first four on the album, are: "Professor Nutbutter's House of Treats", "Mrs. Blaileen", "Wynona's Big Brown Beaver", and "Southbound Pachyderm".
