When I was about 14 years old, I started going to concerts--lots of them. These weren't normal concerts. For reasons that now boggle my mind, I loved heavy metal bands such as Judas Priest, AC/DC and Iron Maiden. During these concerts, I would try to get as close to the stage as possible. Because I only weighed 130 pounds at the time, I would inevitably get pushed to the side of the stage. Although I could see the band well from this vantage point, the drawback was that I would have to stand directly in front of a towering wall of Marshall amps. By the end of the concert, a shrill ringing in my ears silenced the outside world.
Around the same time I began going to concerts, Sony invented the first Walkman. I would listen to my cassettes for hours on end with the volume cranked to 10.
