It depends, some bands I don't really care for the bass, some bands it's essential. If you're looking for bands that not only rely on bass, but thrive on it, look at Deadbolt, Victim's Family, and Nomeansno. Without those sweet low bass licks flowing like sweet audio chocolate they wouldn't be anything. It depends how it's used, if it's just used as background filler because it's expected then yes, bass is worthless. If it's used as it should be, as the solid backbone of the song, carrying everything else on it, then it's priceless.
