The (short-lived) production alias for Digital Underground’s squad of writers and producers, whose name was a clear reference to the real life Underground Railroad network that African-American slaves used to escape from their bondage and into the free states and Canada.
At the time of 2Pacalypse Now’s release, this squad consisted of:
* Shock G
* Money B (Credited as Raw Fusion on 2Pacalypse Now)
* Pee Wee
* Big D The Impossible
* Live Squad
* And last, but not least, 2PACALYPSE, aka 2Pac
This production squad produced the entirety of 2Pac’s debut 2Pacalypse Now (with Pac himself being credited separately as the sole writer and a co-producer), with Shock G as the group’s lead producer, giving the album’s production an east-coast, Bomb Squad-influenced sound, with touches of New Jack Swing. After 2Pacalypse, the squad’s last major production credit was the interlude “Pac’s Theme”, from Strictly 4 My N.I.G.G.A.Z…. Shock G and Money B were credited as Digital Underground for their part on “I Get Around” and Big D was credited for “Papa'z Song” and “Point tha Finga” from the same album.
When 2Pac left the Underground Railroad shortly after due to pending legal issues, and because Digital Underground never used the squad’s name in any of their production credits, they stopped using the Underground Railroad name. 2Pac’s “So Many Tears” was the last time anyone from the Underground Railroad produced a track for Pac in his lifetime.
