This show was cancelled due to the death of a close family member of a Slowdive member. From the band's official site:
We are really sad to announce that we have to cancel the show at Cirque Royal in Brussels tonight due to the death of a close family member of one of the band. We understand how disappointing the news will be and are really sorry to do this.
The show is now rescheduled to Monday May 27th at the same venue. All tickets will be valid for the new show.
We are so sorry for the inconvenience caused. Thank you for your understanding at this very sad time. xx
