Their most well known album was Welcome To The Black Parade with tracks such as Teenagers, Mama, Dead!, and, of course, Welcome To The Black Parade. That was before Danger Days came out in 2010.
Gerard now sports bright red hair and sings about how 'we're all fucking wild.' Rolling Stones called it a pop sound. I disagree. You never hear Na Na Na or Party Poison on pop stations. Instead you hear them on AltNation on SERIOUS XM. Their new sound is obnoxious, but in an awesomely good way.
That's all I can say. Listen to the new album, it explains itself. Laterz for now.
