Ever heard of Emily's Army? I hadn't either till today, but chances are if you're a Green Day fan these guys will catch your attention. Green Day frontman Billie Joe Armstrong produced their latest album Lost At Seventeen, which will be in stores June 11. Why did he help produce this particular bands album though? Well, it just so happens his oldest son, Joey Armstrong(third from the left), plays the drums for Emily's Army. And their not that bad. They just released a music video for their new song "War," although the first official single from the upcoming album is called "Avenue." You can check out both videos below.

Lost At Seventeen is the follow up album to the bands 2011 debut Don't Be A D***. The band is also planning on hitting the road pretty soon as a part of the Warped Tour.
