Composer Alex Buess presents this incredible modern piece for modular saxophone quartet. Dedicated to the world-renowned XASAX quartet. Drawing on a number of music styles, Buess composed this piece for 2 tenors and 2 baritones (TTBB). A multitude of extended techniques are employed, including multiphonics, slap-tonguing, growls, and even 'dental' notes - playing with the teeth on the reed. The resulting sonic palette is both extremely interesting for the audience and a serious challenge for even the most skilled quartets.
