Westlake has always done very well in music. I believe they scored in the top 5 at BOA SA for ensemble music (and didn't even make finals at that). Whats more impressive to me is both the general effect of the show (compared to a a rather boring show in '10), and their execution of the drill (though yes, it did start to become ragged towards the end). I've heard they have a new director that is running the visual aspect of their program, and what ever he is doing, it must be working. They are looking better than any previous year I can remember.
But man, I saw their show at Area D finals, and it was fantastic. The opening brass feature was strong, but definitely could have been louder. They handled the extremely technical parts of Festive Overture well, and while marching surprisingly tricky drill. Their ballad (Variations on a theme by Paganini I believe) fell a little bit flat in terms of what could have been a big hit, but it was made up for in their arrangement of 4 Scottish dances. Got to love those piccolo trumpet solos!
I definitely would not count them out of finals at all, maybe even breaking top 5 at state
Also from Area D, Bowie is shaping up to be a challenger to the LD Bell-Marcus Throne, and already their show is phenomenal. I would bet they make the top 3. The music was strong, and the drill is mesmerizing.
As for LD Bell, I'm not quite certain what happened to them at BOA St. Louis (which is the only one I have seen so far) but it wasn't the LD Bell I expected. Music was good, but their marching simply was not clean enough, even if the drill was exceptionally hard. If they have another show like that, I would not be surprised if they fell out of the top 5.
