Welcome to Guitar World’s weekly roundup of the musical highlights from the, erm, world of guitar. Every seven days (or thereabouts), we endeavor to bring you a selection of songs from across the guitar universe, all with one thing in common: our favorite instrument plays a starring role.What is it? The gutsy lead single from the Finnish guitarist’s forthcoming album, Waiting for the Daylight. With DNA from a variety of sources, Bad Seed’s far from a by-the-numbers, truck commercial blues-rock stomper.
