Winter storm woes have forced cult indie rockers Interpol to scrap a second Canadian show.

The group had to spend more than 40 hours trapped in its tour bus on Tuesday and Wednesday (18-19Nov14) after the vehicle was caught up in a blizzard in Buffalo, New York, en route to a concert in Toronto.

Bandmates Daniel Kessler and Brandon Curtis tweeted winter scene photos and updates throughout Tuesday night, as they fought to stay warm and raided the food and drink supplies on the bus.

It became apparent earlier in the day that they would not be able to honour their touring commitments in Toronto, and on Wednesday, Kessler revealed that Thursday night's show in Montreal had also been postponed due to the storm.

He wrote, "Sadly we have to cancel our show tomorrow night in Montreal..."

Kessler also paid tribute to the emergency workers attempting to dig out stranded motorists, adding, "And can I just say firemen are awesome. They just are yo. Serious ballers during these conditions."

Meanwhile, Curtis revealed he and Kessler were planning another cosy night on the tour bus: "Settling in for another night by the road! Thanks to Lackawanna Fd (Fire Department) for looking after us."

Shows in Boston, Massachusetts on Friday (21Nov14) and Philadelphia, Pennsylvania on Saturday (22Nov14) are still scheduled to go ahead.
