"Wow. These all go back 20+ years to when I was playing quite a bit, but I have to admit that a few of my musical/guitar tastes from my youth make me cringe slightly.
Jane's Addiction: I spent hours and hours picking out literally every note of their first 3 records (Nothing's Shocking, Ritual De Lo Habitual and Strays) all by ear.
Smashing Pumpkins: Every... Single... Note... From Siamese Dream and Mellon Collie, all of which I picked up from the official tab books
Steve Vai: As many notes as I could play from Passion And Warfare, again all from the official tab book
Propaghandi: pretty much every note from their first 3 records (How To Clean Everything, Less Talk, More Rock and Today's Empires, Tomorrow's Ashes) all worked out by ear.
Sunny Day Real Estate: Everything I could figure out from their first 3 records (Diary, Sunny Day Real Estate and How It Feels To Be Something On), again all done by ear
Slayer: You can't play metal and not love Reign In Blood, I can remember getting the official tab book and learning every note I possibly could.
Red Hot Chilli Peppers: Blood Sugar Sex Magik was a great album, I picked up the official tab book and just kept playing until I was note for note perfect.
Pat Metheny: Every note I could play (Which I'll admit wasn't very many) from the Question And Answer official tab book."
