Emily's Army is a punk band consisting of four boys (Cole, Max, Joey, and Travis). They live in Oaland, California and play various clubs (including 924 Gilman Street).
Joey, the drummer for the band, is Billie Joe Armstrong (of Green Day)'s son. But the band should not be compared to Green Day in any way, shape, or form, for they are different.
In my opinion, Emily's Army is a kick-ass band and could bring punk back to the mainstream/today's world.
