Channelview's band director says making music helped in their recovery, even as many students dealt with bruises and broken bones.
"My kids know that I'm very stoic and I'm very firm. But I teared up when I actually saw them in competition because of how hard they had worked. Not only to overcome their music, but to overcome their physical problems or their emotional problems," Channelview's band director said.
The Channelview High School band went on to earn sweepstakes at the UIL contest.
