Internet guitar virtuoso Rob Scallon is no stranger to song challenges. He’s written songs with one string, on the 14th fret and using lyrics crowd-sourced from fans. He’s even done a song with no notes. So now he’s returned with a song written entirely on the fourth fret. It sounds appropriately shreddy, even if you had no idea how many frets were involved in the song. You even get a peek of him with a ridiculous fake beard in a clip.
