Early Life and Career Beginnings

Born on April 10, 1963, in Chicago, Illinois, Warren Justin DeMartini spent his early years in River Forest, Illinois, before his family relocated to San Diego, California. Music was a significant part of his upbringing; his older brothers, Bernard and James, played in a band that rehearsed in their basement, sparking Warren’s interest in rock music. His grandmother also contributed to his musical foundation, having played piano accompaniment to silent movies in Preston, Minnesota. At around seven or eight years old, Warren’s mother bought him his first guitar. However, he struggled with the instrument due to its poor quality and eventually smashed it in frustration, emulating Pete Townshend of The Who. Determined to pursue music, he saved up at the age of 14 to purchase a Cimar Les Paul copy, marking the true beginning of his guitar journey. The first song he learned to play was “Sunshine of Your Love” by Cream, which he mastered by ear.

Warren played his first concert with his band the Plague in front of a small crowd at San Diego’s La Jolla High School at the age of 15. By this time he was emerging as one of the San Diego area’s most talented and sought-after young guitar players. The first year he signed up, he won “Best New Guitar Player in San Diego” at Guitar Trader on Clairemont Mesa Blvd. He graduated from high school in 1981. DeMartini began taking classes at a local college, but in the first semester was invited up to Los Angeles to join Mickey Ratt, the band that would eventually become the highly successful 1980s metal band Ratt.
