Both shows are absolutely killer this year. I would hate to judge these two against each other. Burbank's show is also amazing from the videos I've seen. An absolutely stellar year for the three big Californian groups.
Choreography is simply that - the sequence of steps and movements of the performer. Showmanship can include staging, general effect, expression, pace of show, transitions, costuming and appearance, entertainment value and so forth (varies from scoresheet to scoresheet). In other words, everything NOT vocal. Also, at Burroughs Music Showcase for a time (still may be the case, I don't know) the choreography caption award was considered an award for the choreographer, based on the content of the choreography, not necessarily the execution. However, I don't know how this contest chooses that caption winner.
Los Alamitos Connexion got GC in the Tier 3 division, with Matthew Berry as Best Performer
Los Alamitos Xquisite got GC in the women’s Tier 2 division along with Best in Show and Best Music. Elena Farfel got Best Performer
Is there any reason you predicted Los Alamitos "Soundtrax" second? I'm not sure if it's because of Burbank, but from what I've seen Burroughs' tech crew is not equipped to handle their equipment. I would factor that into any prediction as well, considering last year they got a time penalty at this competition for that same reason.
Schedule added. In typical Hart fashion, there are no times given for individual choirs. Instead, some of the divisions have overall start times. Those are:
3/8, 4:00pm - Middle School Mixed / Middle School Girls
3/8, 7:30pm - Women - Tier III / Mixed - Tier IV
3/9, 8:00am - Mixed - Tier III / Women - Tier II
3/9, 2:00pm - Women - Tier I / Men
3/9, 7:00pm - Mixed - Tier II / Mixed - Tier I
