Roscoe Dash

Johnson started rapping when was at the age of 12, after his older brother introduced him to hip-hop.[3] While attending in high school, he and his brother created a rap group, which consisted of four artists, who went by the name of Black Out Boiz (aka B.O.B.), where his original stage name ATL came from. Though the group has been receiving positive feedback, ATL would eventually leave B.O.B. (Black Out Boiz) and get started in his pursuit of a solo career.[4] He continued recording in his basement and making mixtapes, this hard work led to Jeffrey Johnson going into a meeting with sponsor of the local rap group, who called themselves Travis Porter.[5] He attended Mill Creek High School.

Johnson knew he had to create a new identity to start his music career.[6] He googled names of comic book heroes, and came across the name as Roscoe Dash. Johnson says, "I needed something more marketable. I needed something that would catch the ears and eyes of whoever was listening or reading the name Roscoe Dash and make them want to do research on Roscoe Dash."[7] Roscoe Dash released a song, called "All the Way Turnt Up" featuring Travis Porter, while the group released their mixtape, titled I'm a Differenter 2. However, Dash was only credited as a featured artist.

According to Porter, this was just a mistake.[8] He then met local entrepreneur LA da Boomman in 2009, who then signed him to his production company, Making Moves Inc. (MMI).[9][10] Dash later agreed deals with both Music Line Group after Boomman introduced Dash to the A&R representative Anthony Tate, and Interscope Records distributed Zone 4 after Tate and Dash spoke with music producer Polow da Don, who was the label's founder.[9][10]

Shortly after its original release, Dash re-recorded the track, called "All the Way Turnt Up", featuring a added guest verse from fellow Atlanta-native rapper Soulja Boy. After that version of the song had turned into a radio hit, Dash signed with Interscope Records within the following year. Dash started recording his debut studio album, titled Ready Set Go!, but it was leaked and shipped before the official release date. The following year, Dash was featured on the chart topping single, called "No Hands" by a fellow Atlanta-native rapper Waka Flocka Flame, alongside a Washington D.C. rapper Wale, making the song itself to become a three-time platinum, and earned all three rappers the "Club Banger of the Year" at the 2011's BET Hip Hop Awards, while Dash received a nomination at the ASCAP Music Awards in 2011.[11][12]

In 2011, Dash released his first extended play (EP), titled J.U.I.C.E.. Dash also appeared on Big Sean's hit single, called "Marvin & Chardonnay", in which the song went on to be certified Gold.[13] In 2012, Dash was featured on the cover of XXL magazine, as part of their annual "Top 10 Freshmen list", along with these fellow rappers; including Iggy Azalea, Danny Brown, Kid Ink, Future, Hopsin, Macklemore, French Montana, Don Trip and Machine Gun Kelly.[14]

On August 29, 2014, Dash released his mixtape, titled The Appetizer hosted by DJ Fly Guy.[15][16][17] In June 2015, Dash released the track, called "Catch A Body", in which is currently off of his upcoming studio album, titled Dash Effect 2, under new booking management and is seeking a major comeback after his last few years of silence. In March 2016, Dash released a new mixtape, titled Glitch presented and hosted by his then DJ, DJ Fly Guy.
