To give a short answer, the best thing in IF was most probably what our Bottled-lover friend here said about the mixture of musical orientations from the Jesper-Anders-Björn trio.
What did Anders do on TJR exactly? It sucks to be honest. The singer in subterranean was million times better than Anders on TJR. You listened to Skydancer? Do it, if you did not yet. That has got to be the shittiest vocal performances I heard, and yes, I listened to Rebecca Black's Friday.
On TJR he played it safe. Let me present Moonshield with Anders: "waaah wah wah, wah wah wah wahwah". Now let me present how it would sound if they dragged in some hobo for the streets to do it: "waah wah wah, wah wah wah wahwah". Sure, it sounds nice, I mean it's a pretty melody, but it's all about the music. Not to mention the songs where the growls doesn't even have much melody in them. They are empty as fuck, unless you are reaaaallly into that stuff, but even then, the MDM scene had to be a really sad one if Anders' growls on TJR were to be called remarkable.
It's much better on Whoracle and Colony, but it doesn't have that trademark Anders feel to it which surfaced on Clayman first. When he actually plays around his voice, it's like a beautiful imperfection. You know, that cute girl who has a mole on her face. It's a degeneration, and I'm sure a lot of girl are less attractive by it, but that particular one is a 100 times more sexy thanks to it. That's how I see Anders' power as a vocalist, and songs like Crawl Through Knives, Vacuum, Leeches, The Quiet Place etc. are good examples. I love when his voice cracks, and he's a smart man, because he recognized it's appeal and used it a lot IF songs. Crawl Through Knives is heavy, angry, soft and fragile in one. It's just so cool and makes the song really interesting. Now, that's when I'd say it's challenging the audience, but you are not sure if you are listening to some great metal, some gay singer who whines about the sky, or something entirely else.
But let's look a song I reaaally like in almost every aspect from the old catalog - and is not that mainstream -, which is Worlds Within The Margin. Now, that song is growl all over (yeah, there's the talk, but come on...), but it works. It has a nice flow, a nice melody, and the synth compelemnts the singing so fucking good. Do I want an album full of songs like that? Hell no, even that'd be boring (unlike an album full of Crawl Through Knives, hello Come Clarity!), but a song with full growls, full screams or full cleans can be amazing, just not an entire album, especially not many in a row, at least not from a vocal standpoint. Do we like Episode 666 because Anders' yells THIS IS EPISODE 666? Well, it's certainly not the highlight of the song for me. The guitar kills it, hands down.
Anders' vocals on later records definitely played a key part in international success, but I equally love that music itself as well. What I think is really important here is the DRIVE to experiment with things, and if it was mainly Anders who urged his bandmates to that direction, then yes, probably he is the most important "thing" in the band's history, but given that their early records were heavily carried by the guitarists, while ANders tried to be either not annoying (but irrelevant) or decent (which is not enough to win this vote), an arguement could be made that without those kick-ass melodies he'd never had the luxury to say "hey guys, let's try something new, shall we?".
I also noticed almost everyone here likes his lyrical talent, so let's not forget that either.
Well, TJR could be wrong example so that's my fuck up. Anyway. So it looks like you're really big fan of Crawl Through Knives, which I also like it very much. So I'll give you that song for example. The reason that this song is so powerful is Anders. Guitars are very nice I won't deny that. But the thing Anders did on chorus, the variations (clean to scream, scream to clean) its very amazing and special. If Mikael Stanne or someone else sang this song instead of Anders, I really dont think that this song would that be powerful. After Clayman Anders really shines and becames most important factor of the IF since they did guitar driven songs before Clayman. Another example for me is My Sweet Shadow. Really nice powerful intro,good rifs. But with Anders's vocals song goes another level which made song one of the hits of IF. And I dont think anyone else can does that.
But of course, he always didnt do the right thing. In ASOP, Anders sounds awful and that's the big reason of why ASOP sucks. It's not just Anders fault of course, but he's the main part of it.
