Hail Mary Mallon is a hip-hop group comprised of Aesop Rock, Rob Sonic, and DJ Big Wiz.
The group met each other in the ‘90s and began working together on Definitive Jux–the record label EL-P owned at the time. Aesop and Rob collaborated for the first time on Aesop’s 2005 song “Winners Take All”—the two went on to become close friends. Aesop explained their bond in a 2014 Rhymesayers video
We started joking around. Which is kinda what-kinda a lot of what our bond is was just like being funny to each other.
