4.
The band that defined Alternative Rock as we know it. Hit song "Dizz-Knee-Land" kicked off the alternative rock radio movement.

Unfortunately few other bands with an independent spirit have had nearly the same production values, so this breed of alternative rock fizzled with the band.
Spin "Puzzle" by Dada if you want to know what alternative rock is/was. These current indy guys don't know their way around a guitar, or how to develop a lick, or even how to play at more than a single dynamic level.
