If it weren't for the tragedy of addictions AIC could have been the Led Zeppelin of that generation. Look at their overall body of work before they began to disintegrate: They could do upbeat, aggressive and even thrashy metal...slower, darker groove oriented metal...straight up rock / hard-rock with flavors of blues and even country mixed in...fantastic and highly emotive ballads and even haunting, fully acoustic pieces. In my opinion, there wasn't a thing they couldn't do musically with proficiency, grace and class. All while sounding highly original in their presentation. Definitely the most influential of the "grunge" (whatever that means) era.
