Catfish & The Bottlemen
had a strong 2014, setting them up to have a huge breakout in 2015. To kick off the new year, the Welsh rock band took over David Letterman's stage for their network television debut by performing their single, "Kathleen."
The guys swept through the song with all the ferocity and excitement you'd expect from an adrenaline rushed live performance. On point and in their element, the band proved their intent to become music heavy hitters in the coming months.
Check out their performance below and don't forget to take a peek at our exclusive session with the guys HERE
