Query: ROCK ON!!

I absolutely fell in love with The Music the first time I listened to their debut album... finally a new band that's not afraid to rock however they please - it was impossible to define them without listing off a million ways to describe the band. When I first heard Welcome to the North, my first impression was that they had become more mainstream, but the truth is they are just tighter, funner, and rocking harder than ever.
