Your heart was no doubt in the playing of this song. At first I was thinking : "Hey, how can somebody have the nerve to take such a great artist song and re-record it? Are they just trying to use somebody else's talented riffs?".
Then I realized and thought : I must say, it's obvious there is no doubt you took some time playing and recording this. I thought it turned out great honestly!
Honestly, this is kinda the direction I am working towards with my own music, REAL MUSIC and playing the guitar for real and learning from listening from the greats like Robert Johnson and others. Learning older styles and incorporating them into my own playing and style.
Although I haven't listened to the radio in years because music changed to nothing but copy/paste and steal riffs type of stuff.
Keep on doing what your doing here, because, if that's what your heart wants to follow, ROLL WITH IT, don't let others tell you any different.
This actually sounds GREAT MAN! I was defensive at first hearing it because of the song cover and playing the tones of a legend, but you did mention who wrote the tune and who played it. So it's all good in my world of tones.
Enjoyed hearing this on, and WOW! Keep on Keepin' on!
