Wu-Tang Clan:

Founded in New York City's Staten Island in the early 1990s, the Wu-Tang Clan is comprised of members RZA, GZA, Method Man, Raekwon, Ghostface Killah, U-God, Masta Killa, Inspectah Deck, Cappadonna, and the deceased Ol' Dirty Bastard (ODB). Their name is a reference to a 1983 martial arts film. 

Led by the production of RZA, samples from martial arts films have thematically appeared throughout the group's music, as have samples of classic funk and soul tracks from artists like Rick James, James Brown, and Syl Johnson. As a group, Wu-Tang Clan have three platinum albums among their eight LPs, and the group's complete anthology (including solo albums) has more than 85 full-length releases. More than just rappers, Wu-Tang Clan are entrepreneurs and successful cultural influencers, with an empire that features everything from clothing lines and video games to books and acting credits.

Nas:

Long regarded as one of the greatest rappers of all time, Nas offers audiences some of hip-hop's most powerful storytelling with classic, hands-in-the-air delivery. A live Nas set typically features both critical favorites and pop hits, including songs from his landmark 1994 LP Illmatic — perhaps one of the most acclaimed rap debuts of all time — and selections from the impressive 11 albums that followed. His evocative rhymes have been featured everywhere from New York's iconic Hot 97 Summer Jam to hip-hop package tour Rock the Bells to a performance at the Kennedy Center backed by the National Symphony Orchestra. Following the release of Nasir, a 7-song album executive produced by Kanye West, the lyrical titan will embark on a co-headlining tour with R&B legend Mary J. Blige.
