I just got word from the band director of Galena Park HS.
Galena Park was the top 4A band by a score of about 1000 points higher than LCM, and GP was the 4th highest overall in 4A and 5A. Galena Park however could not accept the 1st place award since they hosted. LCM was ranked 17th overall.
Full results are being emailed to me by his wife in the morning. If noone else has posted results by then, I'll post them.
