I read someone else's review--"music to go to sleep to." What an underhanded comment! I think the reviewer meant it well, but I can't agree. The aptly titled MUTATIONS is a collection of songs, each showcasing a different genre of traditional euro-american music (or personal influence), altered or mutated by Beck here in the modern day. Many think this is his least cohesive effort, but I believe it is a collection of very different songs, all held together by a truly giffted performer. Call it a collage--an attempt by Beck to introduce you to each of his musical influences (with a little of that patented "Beck" twist). One thing missing from this mellow output that we saw on STEREOPATHETIC and ONE FOOT--the production quality of this CD is excellent. I almost miss the raw quality of his earlier "folk" sounding recordings. Evrything here is clean and polished. And once again, he astonishes me with incredibly insightful lyrics. Ther are a few weak tracks on this CD, but the good ones are by far his best recordings to date ("Cancelled Check," "Bottle O Blues," "Diamond Bollocks," "Tropicalia," "Nobody's Fault But My Own"). Songs that can make you laugh, then cry in the same breath. Truly amazing.
