Vincent Lamont Mason Jr. (born March 24, 1970) is a rapper, producer, DJ and one third of hip hop group, De La Soul. Mason is also known as Maseo, P.A. Pasemaster Mase and Plug Three.
Kelvin Mercer ("Posdnous", "Plug One", "Plug Wonder Why", "Mercenary") and David Jude Jolicoeur ("Trugoy the Dove", "Plug Two", "Dave") were already friends when Mason joined the pair to form De La Soul in 1987. The trio came to the attention of Prince Paul, then a member of Stetsasonic, with a demo recording of "Plug Tunin'". Paul facilitated a record deal for Mason and his colleagues with the Tommy Boy label and produced their first album, 3 Feet High and Rising.
