Music was always a part of Brian Jack's family life in Texas as he was growing up. A number of members of the Jack clan were skilled musicians, and the future recording artist was 13 when he decided to keep the family tradition alive by taking up the guitar. Time spent working with a band called the Zydeco Two-Step, an outfit led by one of his uncles, cemented his interest. He gave up the guitar in favor of the accordion when he was a high school student. Jack learned the accordion without any formal instruction and within three months pulled together a band of his own, Brian Jack & the Zydeco Two-Step. The lineup continued to shift for the next 12 months, and eventually the group evolved into Brian Jack & the Zydeco Gamblers. Jack handles lead vocals and accordion. The band also includes his sibling, Eugene Jack Jr., who sings background and plays the drums, as well as bassist Anthony Rowell, guitarist Ben Black, and background singer and rubboard player Jody Lemelle. Jack and his band have appeared at numerous festivals in Louisiana, Texas, and Nevada, and also have performed in Washington and California.
