Diesel Theory is a metal band former in 2001 in Union City,  NJ. They write honest and trend free music… always combining elements of heaviness, melody, and timing in the songwriting process.

Tom Jack destroys both vocally and on guitar, with the inspiration of other guitarist/vocalists like Max Cavalera and Tommy Victor.  Andy Hendrickson is one of the most intimidating bassists and vocalists in the NY/NJ metal scene today.

Joining the lineage which includes Lamb of God and Today is the Day, Diesel Theory recorded their first full-length effort at Austin Enterprises in Clinton, Massachusetts. They were the last band to record at the prestigious High Street studio that was responsible for cranking out The New American Gospel and one of the first bands to sign with Steve Austin’s label, SuperNova Records.
