When a band's debut album is both impressive and hugely successful, it's not often that their sophomore effort makes it seem almost average in comparison. But in the Pit of the Stomach. We Were Promised Jetpacks' grand, accomplished follow-up to 2009's These Four Walls is precisely this rare exception. In the Pit of the Stomach is a huge leap forward from their debut, full of prickly ambition and grand-scale vision, sure, but with no shortage of the hooks and personal engagement that have earned their debut and, indeed, their powerful, wrenching live shows such a wide, devoted following.
