Jurassic 5 is an American alternative hip hop group formed in 1993 by members of two previous groups (Rebels of Rhythm and Unity Committee): rappers Charles Stewart (Chali 2na), Dante Givens (Akil), Courtenay Henderson (Zaakir aka Soup), Marc Stuart (Marc 7); and disc jockeys Mark Potsic (DJ Nu-Mark) and Lucas Macfadden (Cut Chemist). The six piece crew that was formed, came out of the Los Angeles venue Good Life. The group broke up in 2007, shortly after releasing their fourth LP Feedback, citing "musical differences," but returned to the stage in 2013 and released a new track in 2014. The members have continued to release music, the most recent of which is Nu-Mark's 2014 EP with Pharcyde member Slimkid3 (released on Delicious Vinyl).
