About Antero

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 internationally to perform in Venezuela and Canada. Prizes include first prize at the Plowman Chamber Music Competition; silver medal at the prestigious Fischoff National Chamber Music Competition and semi-finalists at the International Chamber Music Competition in Lyon, France.

The distinct cultural backgrounds and personalities creates the Antero Winds’ signature blend and performance style. The quintet strives to present performances that are as interesting and satisfying to music connoisseurs as they are to those with little prior experience with classical music.

Engaging the community

Educational outreach has brought the quintet to schools and communities throughout Colorado. 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.
