While it's not for everybody, the legacy of the underground hip-hop scene cannot be ignored. Possessing its own hierarchy of OGs and up-and-comers, collectives and lyricists, R.A. The Rugged Man has established himself as a cultural fixture at this point.

Case in point, the stacked roster of guest appearances lining his brand new album All My Heroes Are Dead. Those familiar with the underground will likely recognize some of these monikers, from the legendary Ghostface Killah to Atmosphere, Vinnie Paz of Jedi Mind Tricks to Chino XL.
