Bands break up all the time. This is an established fact, and depending upon how many of your favorite band's original members are alive, sane or producing concept albums, it can be a welcome one. The only difference this year is the purely unfair share of fallen rock soldiers that will have ended with it. The announcements of their demise came quickly and with a strange range on the surprise spectrum: Some of 2011's dead bands ended before their time (LCD Soundsystem), a lot of them ended after their time (R.E.M.), and some of them past even the point where they should be reasonably allowed to continue to exist (t.A.T.u.). Below, Backbeat put together the year's five hardest hits to the industry, accompanied by five songs to make you even sadder about your loss.
