I found Nine Inch Nails The Fragile to be a bit full of excess lard/fat, if you will. That being said...
Dream Theater "Six Degrees Of Inner Turbulence"
The Gathering "How To Measure A Planet"
Black Sabbath "Live Evil"
Metallica "And Justice For All" (Yes, the LP was a double album)
Electric Light Orchestra "Out Of The Blue" (same applies)
Manowar "Hell On Stage..Live"
Judas Priest "'98 Live Meltdown"
Marduk "Infernal Eternal" (my fave live black metal album)
Marillion "Made Again" (Hogarth rules!)
Overkill "Wrecking Your Neck-LIVE" (one of the best live albums of all time!)
