The JHS Band has been, officially, nicknamed the "Ambush of Tigers Marching Unit/Force". The Ambush has been ranked in the top ten in Idaho for the past four years. The director of the Band is Mr. Hiroshi Fukuoka. The band currently consists of 20 to 25 members. In 2009–2010, the Ambush became the District 4 State Champions, beating the Burley High School "Burley Bobcat Band", in two out of three of their competitions, for the award, the first time that the "Ambush of Tigers" have ever won the award. The Pep Band has helped the school win the Sportsmanship Award three consecutive years, until the Band and school were beaten out for the award this year, amid controversy, to rival Twin Falls High School Bruins in the IHSAA Girls State Championship Tournament. The Band also lost the Sportsmanship award in the IHSAA Boys State Championship Tournament.
