"It was gruelling. I don't think we've ever actually as a band going out there, worked that hard. Gig, next town, gig, promo gig, promo gig, and it was good," frontman Tom Meighan told Absolute Radio's Christian O'Connell.
''I think the future looks good for us in America because we haven't been there for five years because we had a bit of politics with our record company.
''The shows were great and we were in Middle America, in nowhere place, so once you start getting people interested you're doing okay.''
Meighan also confessed that songwriter and guitarist Serge Pizzorno has already started work on new tracks for their next album.
"I think Sergio's got loads of stuff written already," he added. "I imagine he has because he never stops writing. So I can't imagine when we're going to record a record, not at the moment, probably next year some time."
