I think people are missin the point here.
The facts are :
They released their first single without a record deal and it got to number 47 on the uk chart.
They recorded their first album with no record deal.
They headlined the London astoria without a record deal.
Their philly show at the 1000 capacity venue sold out today in 1 minute. yes, 1 minute!
Their debut album has only been out for 7 months and has already sold 1.3 million in the UK.
No, they haven't headlined an arena tour yet, see above fact! They will be headlin' an arena tour here in the UK by the years end.
They have been touring constantly since last summer, with only a two week break over christmas.
Their second album is nearly finished and they will record it as soon as they can. They hope for it to be out by April.
now if that doesn't make you respect them just a little bit, then I don't know what will.
