Substantial, (born Stanley Robinson), is an African-American MC from Prince George's County, Maryland. He released his debut album, To This Union A Sun Was Born, in 2001 as a collaboration with Japanese producer Nujabes. After gaining significant popularity in Japan, Substantial began work on his sophomore album, Sacrifice, which he planned to release under his Unlimited Vinyl, Ink label. However, longtime friends and colleagues QN5 Music secured a firm distribution route, and signed Substantial in mid-2006. The album saw release in early 2008, to critical acclaim. The video for "It's You (I Think)" has sparked a significant rise in popularity, appearing on MTV and in other major media outlets.
