Chances are, you learned of Leo Morocchioli from YouTube, as he has become a bit of a big deal there. He isn't just releasing covers though. He somehow manages to tour with his band and frequently release video's updating and giving tips to his metal head fans.
While many became fans after some of his more popular videos, like his cover of Adelle’s' "Hello" (watched more than 40 million times now), It wasn't just a run of good luck that gained his 4.67 MILLION subscribers. It was years of hard work, passion for music, and dedication. Leo doesn't just sing his songs, he recreates the metal version, plays every instrument, sings, and then produces the video; filming, editing and of course starring in it. That in itself sounds like a good amount of work, and somehow he manages to release a new song every Friday. To count, he's coming up on 500 songs on my Spotify playlist, which is a pretty good indicator that he's serious about what he's doing!
