I think we've discussed this elsewhere, sorry.
Don't plan on listening to the album, obviously, but this Chuck Klosterman review is fantastic
http://www.grantland.com/story/_/id/7146312/lou-reed-metallica-albumIf we still lived in the radio prison of 1992, do you think Metallica would purposefully release an album that no one wants? No way. Cliff Burnstein from Q Prime Management would listen to their various ideas, stroke his white beard, and deliver the following 45-second pep talk: "OK, great. Love these concepts. Your allusion to Basquiat's middle period was very apt, Lars. Incisive! But here's our situation. If you guys spend two months writing superfast Diamond Head songs about nuclear winter and shape-shifting, we can earn $752 million in 18 months, plus merchandizing. That's option A. The alternative is that you can make a ponderous, quasi-ironic art record about 'the lexicon of hate' that will outrage the Village Voice and mildly impress Laurie Anderson. Your call." Ten minutes later, Bob Rock would be parking his Lexus at the studio.
