About Us
WindWorx Symphonic Wind Ensemble
Our Founding and Journey
In our 20-year journey, we have played and recorded outstanding musical pieces under the baton of our resident conductor, Sean Kierman and guest conductors, Allan Stephenson, Mathew Reid, Phil Golson and Rik Ghesquière and many others, for which WindWorx has gained considerable local and international attention.
WindWorx is a non-profit organisation which aims to provide a unique opportunity for postgraduate musicians from diverse backgrounds to share their artistic talents with the public. We aspire to set a standard of excellence by playing music at an advanced level that stands as an example to the Cape’s many other bands.
In recent years, WindWorx has forged a strong partnership with the UNIVERSITY OF STELLENBOSCH SYMPHONIC WIND ENSEMBLE (USSWE), expanding our commitment to providing an expansive platform for advanced students to showcase their talents.
Amid the challenges posed by the pandemic, which imposed restrictions on traditional performance opportunities, WindWorx demonstrated resilience by establishing a smaller ensemble tailored for corporate events.
Our intimate concerts featuring vocalists Niël Rademan, Lynelle Kenned, and Amanda Osorio, along with the instrumental prowess of Elna van der Merwe in “Rhapsody in Blue” and Peter Martenz in the “Gulda Cello Concerto,” were enthusiastically received.
This adaptive approach not only allowed us to navigate the unique circumstances presented by the pandemic but also showcased the versatility and adaptability of WindWorx. We continue to explore innovative avenues for musical expression and to providing diverse and engaging performances.
Join us on this musical journey as we foster a community of passionate musicians to bring exceptional music to audiences far and wide.
