If you ever wondered what it would sound like if Frank Sinatra sang a Metallica song, wonder no more. This video here is pretty damn cool. Obviously the fan bases of Ole Blue Eyes and Metallica are very different, though listening to a Sinatra sound-a-like sing 'Enter Sandman' is enjoyable.
At least it is to me. I love Metallica, and I've always thought Frank Sinatra has some songs that are cool. 'Summer Wind' and 'My Way' are a couple of examples, though hearing this makes me think the possibilities are endless of what type of songs Frank Sinatra could have sung.
