Tough question but I'd have to go with
The Battle of Los Angeles by Rage Against the Machine
Personally, my favorite non-Incubus album would have to be either Uplifter by 311 or Permanent Waves by Rush.
Americana by The Offspring
That album got me into music!
System Of A Down - Toxicity
hmm this is hard led zeppelin by led zeppelin..lateralus tool...rage against the machine by rage against the machine..gza liquid swords...it takes a nation of millions public enemy
wow this is way to hard.
Ten - Pearl Jam
tough but first one that popped in head...
Blood Sugar Sex Magik - RHCP
