id say the hardest thing for me to learn on guitar is Eric Johnson's songs because he slides his fingers up and down so much but he also stretches his fingers while going up and down scales a million times in one second!!
freakin hard man!!
im also still workin on the Locked and Loaded and Cracking the Whip solos from Yngwie Malmsteen off his album Unleash the Fury
freakin hard as diamond!! lol ok ill stop
