"What makes it so special is that he actually mastered it and sequenced it on his own, this was finished and ready to go. It just means so much more, you know."
The release of the album over the Christmas holidays was timely, Vicky said.
"This year was difficult for everybody. Just missing him so much, and wishing he was here and thinking god, he'd be writing songs about this ... I felt like it was an amazing time to give back, and to also have him around for the holidays. You know, I hope I was able to give something back to them (the fans) for everything they've given to us."
Putting together a video for Chris's cover of Guns'N'Roses' Patience was "gut-wrenching", she said.
"It sounds like a great idea when you say it, and then suddenly you have to do it. My kids sat with me at the table and we opened up boxes of photographs and stuff, and just started going through, and remembering him and talking about him, and choosing them. And then, you know, I'd fall apart.
"It was really hard in some ways, but super cathartic in others. It was a special project that came together and it was kind of fun doing it with our children."
And the couple's 16-year-old daughter Toni is carrying on the family name as a singer.
"It seems like she's following him in that way," Vicky said.
"I think that bond she had with him around music, she continues to pour her heart out with it, for him. It's bittersweet but I also think it's healing for her."

It's one way the family is keeping his memory alive, as Vicky said it's important that Chris is remembered "as a man" and not just an entertainer.
"Undeniably I think as one of the greatest voices of all time, one of the greatest writers of his time, he was an incredible entertainer and performer, but above and beyond he was a man whose family was the most important thing to him.
"He gave with all his heart and it means a lot to me that people know him not just for his music, but for his words, his meaning. It's not just like 'here's a guy with a voice that can shatter glass', or just about his hard-rock story. Chris's story is about all of him."
The grief still catches her unawares, Vicky said. She'll be driving home from the supermarket and one of Chris's songs will come on the radio.
"It's hard to do this in the public eye, the tragic loss. But the support and the love that comes from his fans, there are moments when I break down."
But amongst it all, it's the happy memories that are most important to her - like the moment she met the music legend in Paris.
"I was living in Paris, I was a publicist, and I got a call, because I would work with his management company alot, with other artists they had. And I got a call about Audioslave, and I was like 'oh my gosh'," she recalled.
"But we met, and that was how met, when he came to Paris with Audioslave, launching their first album.
"It was really super special."
The digital album is out now, with the physical album due to hit stores on March 19.
