Just a little over a month removed from the release of XXXTentacion 's Skins album, the late rapper's crew Members Only drop off Members Only Vol. 4, the fourth installment of a series that began in 2015. Naturally, the new project is loaded with previously unreleased material from XXX himself—just in time for what would have been the rapper's 21st birthday (Jan. 23).

The new project, which is a follow-up to 2017's Members Only Vol. 3,  checks in at a hefty 24 songs and, as Members Only's Kid Trunks told XXL, the project features a ton of X. At the time, Trunks spoke on just how the crew were able to make X such a significant part of a project that was almost entirely constructed after the late rapper's untimely death.

"We just know our formula," Trunks shared. "Like, our group has a little formula. It's a good formula, and we know it."

The formula is one that shines throughout the new project, which finds group members like X, Kid Trunks, Craig Xen, Killstation, Coolie Cut, Bass Santana, Flyboy Tarantino, Tankhead and Kin$oul unloading all sorts of different flows over hard-hitting beats. X chips on the melodic end, too.

Check out Members Only Vol. 4 for yourself just below.
