Large Pro's most prominent claim to fame might be the fact that he executively produced Nas' legendary debut album "illmatic" in 94. However, his career in hip-hop started a lot earlier. In the 1990, Large produced Eric B and Rakim's single "In The Ghetto" and in 1991 he put out an amazing album with his group Main Source "Breaking Atoms". Large Professor's production is part of the defining elements of what today we call Golden Era Hip-Hop. The list of artist he worked with goes from Kool G Rap, Rakim, Slick Rick, Nas, Mobb Deep, Busta Rhymes, and Cormega to Common, Joell Ortiz, Termanology,Torae and Reks.
