My favorite rock band would have to be Linkin Park..i love the deep and in pausing voice of Chester bennington and the awesome rap of Mike Shinoda. They both are just awesome and the drummers and keyboard players are good too.
don't have a favourite rock band, It all depends on my mood
but i'll name a few anyway
Metallica, Pink Floyd, System of a Down, Queen, Deftones, Radiohead, Korn, Pantera, Linkin Park, Muse, Marilyn Manson, Tool, Rage Against the Machine etc etc
Metallica really induced me into the music scene. Kirk Hammett shredding it up was a huge inspiration. I was really heavily involved with Jazz/Soul growing up as well but all-around rock band would have to be Metallica. (I like others Led Zep, Nirvan, P Jam, Guns R Roses, Slipknot, AC/DC, Pillar, Aerosmith, etc.)
I don't even know if I answered this yet, but I don't have a favorite rock band. But I tend to like the prog ones, like Pink Floyd, Yes, Rush, Deep Purple. Also, I always liked Queen.
