The Heavy get asked for an encore on David Letterman

If you have ever switched on the radio, TV ,or been to the cinema, whether you realized it or not, the chances are you have heard the music of The Heavy. And with good reason. This British band have been conquering the world with a sound that can only be described as downright dirty. Fronted by Kelvin Swaby, notable fans of the band include David Letterman, who in 2010, enjoyed their explosive live performance on his CBS show so much he begged for an encore.
