What is a masterclass? It’s a private (or sometimes public) session with one of our clinicians to workshop your arrangements, choreography, a few songs, your competition set… whatever you need! Simply indicate your interest (as part of the registration questions) when purchasing your group’s All Access Passes.


AcaBombs are off mic, ‘impromptu’, informal performance opportunities in between classes. AcaBombs are assigned on first-come, first-served basis. Simply indicate your interest (as part of the registration questions) when purchasing your group’s All Access Passes.



BOSS Scholastic Competition

Friday, April 7, 2017

BOSS is back again, and wants *you* to push the boundaries of a cappella performance. Want to be a part of our ever-evolving, consistently innovative scholastic competition? Want to be recognized for your revolutionary take on a cappella? Want everyone in the country to remember your name? Compete at BOSS.

Here’s how:

  1. First, purchase all of your group’s All Access Passes.
  2. Next, make us a video (preferably under 10 minutes). Include the following:
    • A live performance from this academic year of at least two songs (can be song fragments)
    • The reason your group wants to attend BOSS, and what you alone can bring to the stage. Give us an idea of what we can expect, and why we should choose your group!
    • Any other fun things or special talents? Share ‘em.
  3. Upload the video to YouTube, make it private, and send the link to emily@casa.org by 5:00 PM, Friday, February 10.
  4. All groups that apply are eligible to receive the competition guidelines after December 15.

A ‘masterclass’ is a session in which your group works privately with a BOSS instructor or instructors: a chance to receive real-time, constructive criticism from a cappella’s best and brightest! Masterclasses will be available all weekend during class times (Saturday 9:00-5:00, Sunday 10:00-12:00). Masterclass registration is part of event registration and the schedule will be released no later than a week prior to the event.

Certain limited-enrollment workshops and all masterclasses require advance registration, which will open a few weeks prior to the event. We will contact all pass holders when registration opens as well as post details on how to register on our blog and on social media.

Lunch is not included in the pass, although the Saturday schedule includes enough time for lunch at local restaurants.

An All-Access Pass includes admission to both Saturday and Sunday workshops, the Friday evening Collegiate Competition, the Saturday evening Professional Showcase and all afterparties.

Tickets are on sale via Ticketfly. Please see the Tickets section of the website for details.

No, only individual tickets or passes are available to purchase using the CASA Membership discount. If you have some members of your group who are paid CASA members and would like to receive the discount, they can purchase their tickets individually. Make sure they indicate that they are part of your group, and we will have all of your group’s materials together for pick up at registration.

If your group placed 1st, 2nd or 3rd in the 2016 Competition, we will be in contact with you about how to register using your discount for BOSS 2017.
