Dehaven and Calvin Klein both have confirmed alot of the s**t in Ether to be factual. Personally I think alot of the stuff said in the song was Nas speaking vivcariously for Jaz O. I do believe Jaz was in the studio feeding Nas info during the recording of "Ether". Even though their relationship was sour, Jigga never even acknowledged Jaz O on record until after Ether dropped which leads me to believe this.
What's sad is I love you 'cause you're my brother
You traded your soul for riches
My child, I've watched you grow up to be famous
And now I smile like a proud dad, watching his only son that made it
-It might be Nas just sonning the s**t out of Jigga but does that not sound like it more closley describes the relationship between Jigga and Jaz?
In '88 you was getting chased through your building
Calling my crib and I ain't even give you my numbers
-I mean this is exactly what Nas meant when he said "Ether is science". Nas brining up s**t that Jay probably thought no one knew about courtesy of Jaz. So far no one has proven even Jay himself that this is a fabricated event.
And as far as Ether being a bunch of lies: Both camps have had plenty of opportunity to call out each other for any fabrication in the disses so far only a bunch of forum users, blog sites and n*ggas who think they know more than the fans are testimony.
And to addresses Jay saying Ether was not a great record compared to Takeover:
AllHipHop.com: So real talk how was it like around the offices when Nas dropped “Ether”?
Memphis Bleek: [Laughs] It was a gloomy day, for real. When [Funkmaster] Flex played it, I ain’t going to lie, I admitted to myself and had to tell the big homey he got us, he got one up on us. That s**t was cooked crack cocaine right there. Like it was no denying that record was hot as s**t, it was a bunch of lies on that record, but it was still a hot record. One that is going down in history, you know what I mean. We were at Baseline Studios listening to the radio when we first heard it. Jay and everybody was saying this s**t’s hot.
