I think a friend made me a tape in high school. I always respected them. I liked that they knew who they were and stuck to their guns.
Starting at about age 12, I had a KISS phase, an REM phase, a Damned phase, a YES phase, an STP phase, a RATM phase, a Beck phase and now I'm in a TOOL phase. In that order. And I would say Zeppelin has been the only mainstay. I still like all of those bands and there are loads others that I like but I guess that would be the music of my life.
