Manchester, TN – Paul Rosenberg, Eminem’s longtime manager and the CEO of Def Jam Recordings, has refuted reports of Slim Shady using a gunshot sound effect at the 2018 Bonnaroo Music and Arts Festival. According to him, the sound sparking the controversy was a pyrotechnic concussion that Eminem’s been using for over a decade.

“Contrary to inaccurate reports, @Eminem does not use gunshot sound effects during his live show,” Rosenberg wrote on Instagram. “The effect used by Eminem in his set at @bonnaroo was a pyrotechnic concussion which creates a loud boom. He has used this effect — as have hundreds other artists — in his live show for over 10 years, including previous US festival dates in 2018 without complaint.”

Eminem is no stranger to controversy, but this time, it has nothing to do with the content of his lyrics.

Slim Shady has come under scrutiny for using a gunshot sound effect during his set at the 2018 Bonnaroo Music and Arts Festival on Saturday (June 9). The rap superstar used the sound multiple times in his performance, which scared some concertgoers in light of the frequency of mass shootings in the United States.

Multiple Twitter users expressed their outrage and disappointment over Eminem’s performance. Some attendees said they left the festival due to his use of the sound.

Others on Twitter defended Eminem, noting that has been using the gunshot sound for years. Slim Shady has even used it this year without facing such backlash.

Eminem hasn’t publicly commented on the matter at this time.
