Top Bands That Became Famous Overnight
 

I am trying to find out which bands became big relatively quickly. By this I mean that they had limited musical background and ended up becoming big fast, or is this just some rumor that bands make it big overnight?

it's mostly a rumor, but it can be true in the sense that after a band has had their first TV appearance, they became more popular (seemingly "overnight").

Depends.Loads of band make it as soon as they release any music at all.

The only band I'd believe this may have happened to is "Audiovent" because they were all related to incubus, who were blowing up at the time and thusly probably got a contract based on the draft.

Otherwise I can't think of a band who threw it together and really went to #1 save for maybe GnR who weren't overnight, but were pretty damned fast.

Arctic Monkeys jump to my mind as fast as the speed in which they reached their success

As do Oasis.

There was a band named mayham that got big pretty fast. But then they had some kind of murder scandle and tanked or something I don't know.

Well there are plenty of one-hit-wonders that get famous instantaneously, but they always seem to die down eventually. Soulja Boy is one that comes to mind. I knew nothing about it and then one day everyone was singing it. But that might just be due to my un-hipness:p:

Soul-ja boy did come and go pretty quickly but I think its because he really wasen't all that talented.

The story of Soulja Boy is a sad one IMO...

At my school, we had a weeklong field trip. On the first day, on the bus ride someone played Crank That very loudly, and everyone seemed to love it (Not me, i hated that song from the beginning), and it was only earlier that day that I had even heard of this guy. A week later, we came home, and the same kid played the same song, and everyone yelled at him to turn it off.

We were in the woods most of the week, and did not have access to music except on the bus.
