With their 2011 debut Lights Out, the duo of Kacey Underwood and Alice Costelloe, aka Big Deal drew critical acclaim for their stripped down, though deeply resonant music. At once pristine and beautiful yet emotionally fraught, their combined voices spun tales of loss and longing over guitars and nothing else but a cauldron of seething passions.

We posted a Big Deal back in January, but now comes Teradactol, a squalling monster of a track which sees the duo enlist a drummer and bass player to create a gorgeous wall of grungy noise. It is a track to more than whet the appetite for their new album, coming in 2013.

Watch. Listen. Enjoy.
