J-Green can refer to multiple artists.
1. Jemel Green, better known as JGRXXN, J-Green, or Hollywood J is a producer and rapper from Atlanta, Georgia. He is known for incorporating Memphis-style 90's dark and cinematic beats with Atlanta-style trap beats. He began his career as a member of the Blac Teflon record label from 2007 - 2012, and was also associated with Three 6 Mafia and the Hypnotize Minds label.
After Blac Teflon, JGRXXN joined the highly influental Raider Klan rap collective near early 2013, making music alongside rappers such as SpaceGhostPurpp, Denzel Curry, Yung Simmie, Xavier Wulf, and others. As Raider Klan began to fragment, JGRXXN left to create a new collective called Schemaposse in 2015.
Schemaposse grew to a sizeable line up of artists and producers, some of which included Lil Peep, Craig Xen, Ghostemane, Wavy Jones, and several more. Affiliation with similar groups such as Sixset, G*59, and Buffet Boys also helped to attract exposure. Eventually some of the more popular members began to leave, and JGRXXN formally broke up Schemaposse in the beginning of 2017.
JGRXXN would end up reviving the Schemaposse project in the same year, with many members being a part of the original 2015 Schemaposse. He continues to release music with the group to this day.

Despite the success of his first two projects, Jalen had fallen out with his longtime friend, YNW Melly following rumors about the death of his cousin, YNW Juvy. Prior to fixing his friendship, he had been arrested as the police thought he was Melly.
