Much of Robert Plant’s solo work during the 1980s is hit or miss. 1983’s “Big Log,” however, is quite remarkable. From the album “The Principle of Moments,” this is a terrific “night song” if there ever was one. This is a song that sounds just about right when you’re driving at 1:30 am, with little traffic or lights around you … when you’ve got nothing to distract you … and you start really thinking about stuff … especially with those Ennio Morricone-style guitars strumming in the background. Too cool.
