The Cardiff band was set to play the city’s Think Tank venue in Times Square.
But fans were told of the fire and informed that the show would be rescheduled at a later date.
None of the band members was injured but key equipment was damaged.
A statement read: “Some of you may of heard but unfortunately we have had to cancel the show tonight, there was a fire on the bus today which has damaged some of our equipment, which has left us unable to play tonight.
“We are all ok, just a little shaken up. We’ll be rescheduling the show, so keep an eye out for this, all tickets will still be valid
“Thanks for your understanding guys, and hopefully see you soon.”
