Sergeant Haaker has been in Los Angeles since leaving the U.S. Army Band in 2014. He performed thousands of shows with many different groups including the Army's first Metal band, "The Four Horsemen of the Arockalypse". His first tour was a 13 month mission in Iraq, playing metal covers for troops and locals. He recalls, "The first great show I ever played was for 200 soldiers at a tiny outpost. They built us a small stage outside, pulled up armored trucks to use as stage lights, and drank non-alcoholic beer as they moshed and raged to Killswitch Engage and Lamb of God covers. It was clear, they desperately needed that show... I started taking music seriously after that." Upon return, he performed stateside with big bands, jazz combos, country ensembles, and lots of wedding bands--further developing his vast repertoire and unique sound.
The moniker Groove Juggernaut started as a reference to Stephen's diverse style, forged by intensive on-the-job training and refined by countless hours of study and practice. The term has since become synonymous with his indomitable spirit. Devastating personal trials and professional setbacks fail to tamp the fire that has burned since he was 5 years old, banging on pots and pans. Undeniable passion and humble confidence birthed by failure and triumph alike has created a juggernaut--forever learning, exploring and grooving.
