I’ve had a guitar since I was 12. I’ve picked at it from time to time but would like to get serious with it. I’d like to know what the best blues songs to practice with would be. Song names and the original artists who performed them would be grateful. If not blues songs, what are the best songs in general to play to progress in guitar skill. Please and thank you.
