Hmm, I would have to say Pink Floyd's The Wall album. Most Notably 2 songs. Comfortably Numb, and Empty Spaces/what shall we do now. Also the 2 songs from Wish you Were Here (both tracks of Shine on you crazy diamond) and Have a Cigar. After I got started with those, and guitar is when I found all the other bad ass guitarists. I was around 17 years old, practiced a lot, but have slacked off the last couple years, don't really practice, as I focus now more on song writing and recording. (and still rusty at guitar playing for slacking so much lol) I am now 28 years old.
