Given the album's concept, Petting Zoo is a perfect introduction to the band. It eases new listeners in, and still acknowledges their weirdness through songs like "Constantinople" and "Smelly Tongues".
Petting Zoo follows a reverse time pattern; the first two tracks are from their upcoming album, Demons Dance Alone, and then we have one track from the Icky Flix soundtrack, four tracks from Wormwood (two of them are from Roadworms), one each from The Gingerbread Man and Our Finest Flowers, two from Freak Show, two from Residue Deux, one each from Intermission and The Commercial Album, two from Duck Stab, and one each from Fingerprince and Meet The Residents. The album closes with the end theme from the Icky Flix soundtrack.
I was quite surprised to see a Fingerprince track in this compilation. With all that being said, I totally recommend this record for new listeners, and it's a nice little addition to old fans' collections as well.
