At the age of 13 he started going to punk rock shows, which broadened his imagination for the type of music he'd come to play.Dan cites his influences as Jimmy Page, Billie Joe Armstrong and Johnny Marr to name a few. Dan soon tried his hand at writing his own material. He says alot of his material is written based on personal experiences throughout his life. Dan picked up bass shortly after this.
