Grammy-winning rapper Eminem might have to show fans how much he appreciates them after they lashed out over his weekend Wembley Stadium concert in the United Kingdom. #payup

According to reports, bad sound quality during Slim Shady’s set sparked some backlash.

Eminem’s second Wembley Stadium show took place last night (12 July), but was once again marred by sound issues which left many fans demanding their money back. The sound issues were first reported by fans and critics after the first of Eminem’s shows on 11 July, with Club Wembley tweeting to assure fans that they were “aware of sound issues”, and that they will “update you in due course.” (Gigwise)

The venue responded to the fans’ concerns and apologized for the experience.

The account then directed many unhappy fans to email [email protected], but the email response they received, which merely said that “best efforts were made to rectify sound and to contact promoters”, before apologising for the inconvenience, was not enough for those who felt their experience was ruined.

Em’s longtime mentor Dr. Dre shared a moment at the show heading into the weekend.

Eminem became last night (July 11th) the first rapper ever to headline Wembley Stadium in London. The 90,000-capacity venue is to be the ‘home’ of the Detroit MC during two consecutive days, Friday and Saturday, as part of a mini UK tour. At the opening show, Eminem performed all of his hits and sent his thousands of fans to frenzy. However, the highlight came when Em’ brought out his mentor Dr. Dre. The ‘Beats’ headphones boss performed a few classics including “Still Dre” or “Forgot about Dre”. (Direct Lyrics)

Despite the high-profile event, reports claimed fans were left unsatisfied with Slim Shady.

There were those who didn’t love Eminem’s first Wembley concert, though. The Telegraph’s Neil McCormick was sent to Wembley to review the “Monster” rapper’s spectacle, and what did he think of it? “Fans should demand their money back” is the headline of his article, so you can deduce he didn’t love it, ha. He blasted the poor quality sound system. (Direct Lyrics)
