Oddly enough, my favorite act growing up wasn't a band at all, it was Michael Jackson. I loved the grandiosity and high energy of his live performances as well as the ways he progressed the art of film-making with music. I didn't start really listening to bands until much later. My first favorites would have been mostly Punk groups such as MxPx, Misfits, NOFX, and various acts from both Fat Wreck Chords and Tooth & Nail Records.
The answer hasn’t got any rewards yet.
