On one hand, I see how using "attitude" as the definition can apply, but at the same time... Punk musicians have a certain raw, unpolished approach to their instruments whom turn white noise into songs, ballads, etc... It's as if they take a broken radio and force it to work by banging on it..

What I'm hearing in the band you mentioned is a fusion between Rock n Roll and Funk.. and a very clean, refined sound as opposed to a dirty, in your face, choke slam....
