Jerry talking more about Mad Season in a 1996 interview:

Guitar World: Speaking of Layne, what do you think of Above, the Mad Season album?

Jerry Cantrell: I think it's fucking great. I totally have to 'fess up-I was jealous as shit when I first heard it. It's like somebody taking your girlfriend out. [laughs] But after that initial reaction, I went and saw them play at the Moore Theater and I was so proud, I was beaming for them. I almost started crying while I was watching them because it was so cool. Then I felt pissed again because I wasn't up there playing! [laughs] I talked to Layne a lot about the record. It was good for him because it blew a bunch of shit out of his head. I've been credited for being a writer and putting out a lot of material with this band and sniff, so I think it was real healthy for him to be able to do that. I have nothing but the greatest respect for the guy. And that record's very soulful. There are some real low, cobwebby passages on that fucker that are cool as fuck. Layne has the most beautiful way of saying something horrible I've ever heard.

The fact that he said he got upset about Layne doing the Mad Season thing just shows how much Layne meant to him.

The Mad Season album Above is a masterpiece. Jerry knows he can’t say anything bad about it. It’s pure musical magic. You can’t hate something like that.

Everyone should admire someone who is being 100% honest.

Jerry on Layne joining Mad Season: “it’s like someone’s fucking your girlfriend”

I’m so glad Layne finally, got the chance to fully express himself.. and we now, have a feel… for who Layne was, musically

Jerry is so honest bless him

Jerry should get more love than he does. Jerry is a real honest guy and very secure with himself. Intelligent both emotionally and cognitively. That's the guy I'd want to go out with.

Jerry was the cog that made AIC run. He's so down to earth and knowledgeable about human interaction and being open. Love the guy

so that part when kurt said he was doing coke with alice in chains all night wasnt wrong after all

I fucking love Jerry Cantrell. My sanity exists because of his musical acumen

Love Layne…but Jerry is one of the greatest American song writer of all time…damn glad I got to enjoy his music in my lifetime…keep rockin man!

It's kind after Rare to see a Band like AIC where the members are actually Friends and Legitimately care about each other! Most bands  you see can't actually stand one another but AIC were different and it shows in the quality of their music

Interviewer: "blablahablahblah....."
Jerry: "Sure"
Interviewer: "blahblahblahblahblah....."
Jerry: "Yeah sure"

Jerry always struck me as a class act. While so many of his contemporaries would give goofball interviews where they were  intentionally weird and evasive, Cantrell’s interviews are always coherent and thoughtful. I know that music journalists can be clueless idiots, but I feel Jerry’s approach shows respect for his fans, who are really interested in what he has to say.

Jerry's an underrated legend. Thats all I have to say about that

Mad season was the best!!

God opened the heavens and gave the world Mad Season to let the world know that Layne was a phenomenon outside of the realms of just one band. A magnificent album and a great use of talent.

Jerry loved Layne like a brother. During the later years when Layne wasn't showing up for sessions, costing studio time, being so high he couldn't perform, of course he got angry at Layne! Who wouldn't when you have to watch your lead singer and best friend slowly killing themselves? I'm sure the frustration was paramount. In turn, the guilt and shame caused Layne to retreat further into his shell because he saw it as judgement. No win situation. Dang it Layne! We would all have loved to shake that beautiful soul with so much talent and worth until he WOKE UP. We miss and love you, Layne.

Man I really love Jerry, he’s so intelligent and self reflected, truly an underrated genius
