It was gonna happen, Fabric is Matter's sister club. It was just the easiest option for them.
Matter owners also blamed the closures of the Jubilee Line for engineering works for the failings of the club. That's a complete pile of bullshit - Matter has been in financial trouble for ages, it is because of piss-poor management that the club has closed.
The jubilee line services the O2, which is where Indigo is. I doubt they'd of had this Hospitality there as it would contradict their excuse for the club closing. I guess the Hospital crew would have some sort of deal with Matter with regards to hosting nights at the club, and where tickets have already been sold for the next event Fabric was the only choice. If such a deal exists then they should break it off after the next Hospiality and host events elswhere, not at shitty Fabric.
It's a good club, but if you think the shutter-glasses, glow-stick waving fannyholes from Matter are bad....just don't go to Fabric.
