Fall Out Boy tone it down a notch on 'Young Volcanoes,' which is a bit ironic given the explosive title. However, it suits them beautifully.

The band posted the track on their YouTube account along with an announcement about their Save Rock and Roll arena tour tickets going on sale today (April 5).

'Young Volcanoes' is a far cry from lead single 'My Songs Know What You Did in the Dark (Light 'Em Up),' and follow-up promotional single 'The Phoenix,' which were both pounding, heavy anthems. 'Young Volcanoes' boasts a sing-along hook, hand claps and "whoa-oh" refrains. The pop-punk quartet are determined to save rock and roll, but in this track, they're rescuing pop and folk, as well.

The song is indelibly catchy and also a bit reminiscent of fun. -- and yes, it is fun, especially with lyrics like, "We will teach you how to make boys next door out of a--holes."
