  • Rajaton
  • Musae




Saturday Night Performers

The Finnish word Rajaton translates as “boundless” – a word that so accurately describes the way this six-voice a cappella ensemble approaches music. Regularly performing around a hundred concerts and workshops each year, Rajaton exposes their audiences to the kind of diversity of repertoire, singing style, and stage presentation that has made them a phenomenon on the world stage.
Performing at concert halls, churches, jazz and choral festivals, this distinct group of musicians approaches all styles of music with the same level of commitment and integrity, making it difficult to imagine an audience that they could not inspire, or a type of music they could not make their own. In their native Finland, Rajaton is a bona fide pop phenomenon, successfully bridging the gap that often exists between classical and mainstream convention.
Rajaton has released 16 different albums. In 2017, Rajaton celebrates 20 years of music-making with one double platinum, three platinum and eight gold records in Finland under their belt, as their worldwide record sales are drawing over 400.000 copies altogether.
Ever seeking new artistic challenges, the group has grown immeasurably through collaborations with other a cappella artists, including The King’s Singers and The Real Group, as well as productions with film directors and choreographers. But it is perhaps their deep passion for choral art, their generosity of spirit and their sheer enjoyment of singing that has won the hearts and acclaim of audiences and critics everywhere. Their energy – infectious; their ability to entertain and inspire – Rajaton!
The voice is boundless.


Saturday Night Performers

Musae is the leading female contemporary vocal band on the American scene. Comprised of a cappella superstars from New York, LA, Atlanta, and Houston, these women move audiences all over the world with their fresh, fierce sound. Musae is home to veterans of NBC’s “The Sing-Off,” Pop TV’s “Sing It On,” the popular film “Pitch Perfect 2,” ICCA champions, and skilled music instructors and audio engineers. Musae has headlined some of the most prominent music festivals both in the U.S. and abroad. With world-class performances, award-winning recordings, and industry-leading workshops, Musae seek to inspire and educate young artists and performers everywhere to create music and spread harmony.

Featured Instructor: Erin Hackel

Erin has been an instructor and masterclass leader at CASA festivals for several years, and her classes are always both sought after and well attended. This year, we’ll be doing something really special with her – a long-form, auditioned masterclass dedicated entirely to solo singing. We’ll have more details for you on how you can take advantage of this unique opportunity in the coming weeks.


erinheadshotDr. Erin Hackel is an Assistant Professor at the University of Colorado, Denver. She received her Bachelor’s in Vocal Performance from James Madison University, a Masters in Opera from Binghamton University and a Doctorate in Voice Performance and Pedagogy at the University of Colorado, Boulder. She is an active performer with Central City Opera’s Outreach Ensemble, and has been a featured soloist in many Colorado vocal ensembles.

Dr. Hackel’s award winning a cappella groups, MIX and Lark have traveled across the United States and Europe competing and performing. Both groups have been BOSS and SoJam champions, recipients of multiple performance awards, and have won multiple Contemporary A cappella Recording Awards (CARAs). MIX and Lark have been praised for their innovation and professionalism and have been singled out for their boundary changing work in collegiate a cappella.


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.
