HRD was a hip-hop group from Portland, Oregon featuring members Big Nutz and Raw Dillz. Since their 2011 debut, they serve up tracks thick with heavy, textured beats and dense webs of rhyme.
Prior to the release of the second album, the group was also known by the longer version of the name, Hundred Round Drum. Big Nutz was also previously involved with Portland gangsta rap group 5 Oh Trees.
The group is no longer active as of 2021.
