I've always listened to The Beatles, since I was very little (my dad's a Beatle freak), but that was the only good band I listened to. What really got me into Rock n' Roll when I was 10/11 years old was hanging out with people who listened to Nirvana, SOAD, stuff like that. And my sister had just bought Live Era, I think that was the main thing. I also have this cousin who is crazy about Iron Maiden, he would come to my house and we would listen to Maiden all day and play that game, Ed Hunter.?
I can't say it was one band only, quite a few actually, but mainly the ones mentioned above.
