I might be a bit bias with Silverchair, they pretty much got me into what im listening to today. Years and years later music is still a huge part of my life, although my taste in music has evolved there are some bands out there that just stick with you, Silverchair is that band that stuck with me. More specifically Frogstomp, to this day it's still one of the best albums I've ever heard. It's not super technical, 8000 bpm's, it's fairly plain, keep in mind it's been out for ages now.
But It's still catchy as hell, Daniel's voice is impossible not to sing along with. And how old were they? lol like 17 when they wrote this album? will always love this album.
