Warren is the lead guitarist of a popular American rock band, RATT, that has sold millions of records.
He was born in April 10, 1963 in Chicago, IL, as the youngest brother of five. Since his brother, James was playing in a band, and there was always music in their house, it was inevitable that he became interested in rock music.
When he was around 7, his mother bought him a guitar, but he didn't know how to play it, and he smashed it just like Pete Townsend of The Who did on stage.
For many years after the incident, he never got a chance to have another guitar, but when he turned 15, he managed to buy one for himself with the money he got at Christmas. He took some lessons to learn basic guitar techniques, and formed a band called Plague. In 1979, he played his first gig in front of a small crowd at La Jolla High School. As he played with other local bands, his name started to become known as a young talented guitarist in San Diego.
Some years later, Warren who at that time was playing in Enforcer joined Mickey Ratt, which later became Ratt, to replace his friend, Jake E. Lee.
Warren's talent as a guitarist fully flourished with RATT and they had huge success in the 80s.
Now in 2013, Warren is still playing with RATT. His guitars and music keep attracting not only old fans, but also young generation all over the world.
