Eminem fans have voiced their anger on social media after the rapper's Wembley gig was hit by sound issues.
Members of the 80,000-strong audience in the stadium on Friday night criticised the poor speaker system, which left them struggling to hear the global star.
And critics also slated the sound quality, suggesting that fans would be justified in demanding a refund.
However, Eminem has not yet issued a statement because he is still trying to find out why the speaker system was so poor, according to reports.
Disappointed by their experience, a number of Twitter users took to the site to complain about their evening, with many exhibiting their sense of frustration after paying a lot of money for their tickets, which were priced between £75 and £99.
