(CNN) The Spice Girls kicked off their highly anticipated reunion tour in Dublin on Friday night, however some fans were left disappointed after complaining of "awful" sound problems during the show.

It was the first time the 90s girl group had performed in seven years, where more than 70,000 fans watched Emma "Baby Spice" Bunton, Geri "Ginger Spice" Halliwell Horner, Melanie "Sporty Spice" Chisholm and Melanie "Scary Spice" Brown perform the band's biggest hits.

However, some fans complained on Twitter about how they struggled to hear the group.

"There's something wrong when the crowd at @spicegirls concert are all sitting down because no one has a clue what song is on because the sound really is THAT bad," one user wrote.

While others said it was the "worst sound I've ever heard at a concert" and that "loads of people [are] leaving."
