From the 1979 album “Bullshot,” here’s another nasty, disreputable slab of menace from the incredible Link Wray. Aside from the title spoken at the beginning, “Switchblade” has no words. However, trust me when I say that this track is far more volatile than even the crudest Marilyn Manson song. This is dangerous stuff, even more so considering Wray was around 50 years old when he recorded this.
