The Dublin band recently announced new album 'Romance'
It's safe to say that Fontaines D.C. are one of the biggest Irish musical exports in recent times.
The Dublin band have made huge inroads Stateside in recent years, with their second album 'A Hero's Death' nominated for a Grammy award a few years ago, not to mention their extensive touring in the US.
Grian Chatten and his bandmates will release their fourth album 'Romance' in August and are currently on the promo trail with its lead single 'Starburster'.
That trail led them to perform on 'The Tonight Show with Jimmy Fallon' last night - although it's not the first time they've played the high-profile talk show, having made several appearances on it over the years.
They're heading out on a US tour this summer and will also play their biggest hometown shows to date at the 3Arena on December 6th and 7th.
