I was introduced to Nine Inch Nails by my twenty something son, who is a massive fan. Like a lot of kids in their early twenties, the concept of the music is easily as important as the melody, harmony and rhythm. Here’s where groups like Nine Inch Nails rule. Fronted by musical dynamo Trent Reznor, the ID, soundscape, sheer style of Nine Inch Nails (NIN) has jumped the cult shark. And, with Hesitation Marks, NIN’s first mainstream studio (Columbia) album since 2007, the public’s going to jump all over this.
