Roger Waters made the greatest show ever with "The Wall Live In Berlin" (big concert in 1990, about a year after the Berlin wall fell). Confortably Numb guitar duo by Rick Di Fonzo and Snowy White.

May I recommend High Hopes by Nightwish? I think it's much better than Pink Floyd. More emotion. After listening to this one, the original seems so sterile.
Guitar mastery at 4:50.
