scatter band
n.— «They’re known as a “scatter band” for their lack of formation.…“What happened was, we had a band director who was fired in 1963,” says Amit Aggarwal, who plays tenor sax. When a graduate student was brought in to lead the band, he said, “no one wanted to follow, and they went on strike.”» —“Stanford’s mad March” by Karen Lee Ziner Providence Journal-Bulletin (R.I.)
