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.
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.)
