Certainly you will know many guitar and bass guitar covers that are on youtube.
Musicians add them to show what they are and how they can play. The Internet is full of such coverages. But we have found a cover that is really interesting and humorous.
Throughout the song, the player plays one single tone on one line. It’s a bass guitar cover for Lose Yourself by rapper Eminem. What are you saying? Could you do that too? :-)
