The thing is, ever since they hit the big time with the Black Album Metallica have had this stick up their arse about being seen as 'legitimate'. It was at its worst during the Load era, with the attempts at blues-rock, Achtung Baby ripoff sleeve and THAT Marianne Faithfull guest spot, but there's been this sense of embarrassment at them being 'just' a metal band ever since. Hence the terrible orchestra shows; hence the fucking around with the arrangements and production on St. Anger, which was essentially them trying to have their cake and eat it ("OK, we'll give you a metal album but we're still gonna be all avant-garde!") Basically, they wanted to be any band BUT Metallica. It's a big part of why they're in such a creatively fucked-up state in Some Kind of Monster; they literally have no fucking clue who they are anymore.
Death Magnetic seemed to see the band come to their senses, but Lulu is social-climbing Metallica back with a vengeance. As with their other attempts at being 'arty', it also shows that they've lost none of their knack for stunningly bad career decisions. It's very clear that they took on this project a) Because this kind of attention from such an art-rock icon gave them the vapours, and b) For the cred they thought the collaboration would bring them.
Problem is - much like St. Anger - nobody seemed to be putting any thought into making it listenable. Basically, Reed and Metallica don't mesh. I've always considered Reed vastly overrated (So you'll have to account for slight bias on my part), but he sounds terrible on this album - out of key, out of time and in complete ignorance of what the music's doing. Hetfield's backing vocals are simply comical, his attempts at high notes on Why Do I Cheat On Me literally spine-curdling. Metallica have some great musical moments (The Iommi-esque riff in Frustration, the dreamy Junior Dad) but mostly sound out of their depth. They've boasted a lot in interviews that a lot of the songs were one-take affairs that were put together at the last minute, and boy does it sound like it.
Oh, and the lyrics... Jesus Christ. My new tagline under my username is a lyric from the album, and it's not even the worst line on it. Imagine Grandpa Simpson loitering outside a Metallica rehearsal reading from 'My First Erotica Book' , and you'll get the gist. The album's based on a pair of late 19th Century German plays about a homeless girl who becomes involved with a string of wealthy, self-involved men, but Reed's so enamoured with the sordid stuff you never really follow what's going on.
And on that note - because I've not heard one person ask this question since this stupid project was first announced - what the fuck has Metallica got to do with 19th Century german sexual politics anyway? When I think of sexually-exploited country fraus, I don't think of Metal Up Your Ass.
Lou Reed might, though. Fuck, I might be giving him lyric ideas. I might have just enabled LULU 2: METAL UP YOUR ASS.
Fucksake.
