I am learning Master of puppets, pretty straight forward for the most part the hardest parts I think are timing,tempo and execution of the chords, need tight rhythm. The solos will be the real hard part
It is a pretty well known song if you are into metal so there is many good tabs and videos out there.
I like Fade to Black by Metallica. Other good ones are Eyes of an Angel by Impellitteri, Secrets by Hammerfall, Katherine Wheel by H.I.M., and Endless Sacrifice by Dream Theatre.
“Freight Train” as played by Elizabeth (Libba) Cotten. I learned it on 12-string and was able to adapt the style to several other songs in my repertoire.
