About Antero

artistic sensitivity and exuberant stage presence

Known for their artistic sensitivity and exuberant stage presence, the award-winning Antero Winds have been attracting attention worldwide as a talented and engaging young international woodwind quintet. The Antero Winds began their work together as the Arundo Winds, the graduate woodwind quintet in residence at the University of Colorado at Boulder. While serving their Rocky Mountain community, the Antero Winds have also traveled the world to perform, compete, and educate, always striving to present performances that are as interesting and satisfying to music connoisseurs as they are to those with little prior experience with classical music. The distinct backgrounds, personalities, and styles of the quintet’s members combine to create the Antero Winds’ signature blend and performance style.

  • Silver medal at the prestigious Fischoff National Chamber Music Competition
  • Semi-finalists at the International Chamber Music Competition in Lyon, France

Engaging the community

Educational outreach has brought the quintet to schools and communities throughout Colorado and the wider world. The Antero Winds have had an ongoing relationship with the Aspen Music Festival and School, which has brought them to Western Colorado for a series of mini-residencies with the public schools in the Roaring Fork Valley. They have also played school programs and led band clinics throughout the Denver metropolitan area. In 2006, the quintet traveled to Caracas, Venezuela, where they worked with students at a local FESNOJIV (nationally sponsored youth orchestra) school. These educational programs play a central role in the Antero Winds’ mission, and the quintet is constantly seeking new opportunities and approaches to share their passion for music with students and community members of all ages.

South African native Dr. Cobus du Toit is praised for technical facility that makes everything look easy (Opus Colorado) and rich tone that is especially impressive (Herald Tribune). Pretoria News declared: “du Toit makes you believe the impossible. With du Toit in flight one is never aware of technique alone. He is driven by purely musical inspiration.”

A strong advocate for the musical arts, Cobus is an avid soloist, chamber musician and pedagogue who has recently joined the faculty at the University of Massachusetts Amherst. Cobus can be heard live in concert across the world with summer performances in Colorado, California and Indonesia.

As an international soloist and chamber musician, Cobus has performed with orchestras in Russia, South Africa and the United States and on concert series in Taiwan, Japan, Germany and France. Cobus has been a prize winner at over a dozen competitions which include the 1st UNISA Southern African National Competition for Woodwinds and Brass, the Byron Hester Competition, the Myrna Brown Competition and the SAMRO International Scholarship Competition.

In addition to being the principal flute for the Boulder Chamber Orchestra, Cobus is also the flutist for the Antero Winds, a professional woodwind quintet that has been prizewinners at both the Plowman and Fischoff chamber music competitions. Cobus self-produced two recordings available through online platforms: Tríptico with classical guitarist Patrick Sutton and Mythavian with pianist Doreen Lee.

Cobus received his Master of Music and Doctor of Musical Arts from the University of Colorado at Boulder and a Bachelor of Music from the University of Pretoria. His principal teachers include John Hinch and Christina Jennings.

An avid composer, Brian has written works for orchestra, concert band, mixed chamber ensembles, and various solo instruments. In 2012 he was commissioned by The Playground Ensemble to compose a companion piece to Olivier Messiaen’s pivotal Quartet for the End of Time. The result was Fragments of Om, a septet which was premiered by the group later that year. His chamber trio Contradances (for bass clarinet/contra-alto clarinet, vibraphone, and violoncello) was also premiered by The Playground, and it appears on their debut recording Dreams Go Through Me. His most recent works include Beneath a Solitary Sky(clarinet/bass clarinet and laptop), and ubuntu (jazz ensemble and laptop). The latter was premiered live on KUVO 89.3 FM.

A native of Kankakee, Illinois, Brian studied music at the University of Illinois at Urbana-Champaign from 1987-1989. He has performance degrees in clarinet from the University of Colorado at Boulder (BM), the University of Denver (MM), and the University of Northern Colorado (DA).
