The Juicy hitmaker, real name Christopher Wallace, was killed in a drive-by shooting in Los Angeles in 1997, aged just 24.
Now his former wife, R&B singer Faith, is working on a number of projects to keep his memory alive, including her previously-announced duets album, The King & I, which is expected to be released this September (16).
During a new interview on the Dame Dash Radio Show, Faith revealed the recording is in its "finishing stages", admitting she is surprised at how well the songs are turning out with the help of modern technology.
"I had no idea how I was gonna even go about it but it's been coming along pretty awesome (sic)," she smiled.
Faith is confident fans will love the previously-unheard material, which she has been developing with her former mother-in-law, Voletta Wallace.
"If he was alive, I know we would've done something like this but the way it's coming together, the way I'm using his vocals, it's just giving his stuff new life," she gushed. "I think people are gonna really enjoy it."
Faith is also in talks to use hologram technology to create a lifelike version of the legendary hip-hop star so fans can enjoy a joint performance of the tracks in the near future.
"We actually are in development with a hologram, but I don't necessarily know to what extent I'm gonna perform with it," she explained. "I want to debut it in the first video for the album, and maybe use it a little bit performing live. But that depends on a lot of things."
Faith also touched on her hopes to turn her 2009 book, Keep The Faith: A Memoir, into a stage play, which will document her life with Biggie.
The King & I isn't the first Biggie collaboration album to be released following his death. His mentor and record label boss, Sean 'Diddy' Combs, took charge of 2005's Duets: The Final Chapter, which featured remixed collaborations with Jay Z, Eminem, The Game, and Missy Elliott, among others.
Meanwhile, if Biggie does return to the stage as a laser image, he won't be the first hip-hop icon to rise from the dead. Dr. Dre and Snoop Dogg stunned fans at California's Coachella music festival in 2012 by performing alongside a holographic projection of Biggie's rap rival, the late Tupac Shakur.
