I love Mumford and Sons, but they aren’t rock. IfIwant rock,Ilisten to Foo Fighters or The Joy Formidable or Queens of the Stone Age or something.Ilisten to Mumford and Sons and Blind Pilot and bands like that because they AREN’T rock. Sometimes you just need to cool down. To compare The Lumineers to Green Day is simply incompetence about what music encompasses. It’s not rock, but it’s still damn good music.
