21st Century (2010). From Cuban composer Tania Le˘n, we have an exciting work for brass quintet, named for a traditional mixed drink on the island of Cuba, consisting of rum or aguardiente with coconut water. It can also be defined as "a musical work in which grooves emerge like the brief patterns formed when stirring a drink. As the sonic concoction swirls towards its conclusion, the players let out a aoko!' celebratory toast."
