Classical improvisation can be tricky business. There aren't standard rules anymore, and there are very few standards to work with regarding ensemble improvisation in classical music (save some Baroque continuo parts); anyone entering the business in the late 20th century or the early 21st century would be left with very little idea of what to do.

However, the late 20th century saw a small but significant group of classical musicians become interested in the concept of improvised music. These musicians had to work with very little to recreate a style of music called 'classical improvisation'; among these people was Texas composer and pianist Robert Avalon, who developed his own very free concept of what classical improvisation should be and how it should be created.

Robert Avalon combined his experiences in Holland's free improvisation scene with his own knowledge of past improvisors in classical music to generate a unique understanding of classical improvisation, which he passed on enthusiastically to his friends, his colleuges, and his students. Among his last students were the members of HSPVA's Composer's organization, to whom he insisted improvisation be a part of performance practice.

The Uncertain Outcome ensemble developed in order to carry on the art of improvisation which Robert left behind after his sudden death in April of 2004. Since then, its membership has extended to Robert's composition students and a number of newly aquired members who have picked up classical improvisation. The ensemble now does several performances a year, and records a great deal of intriguing and unique music for all kinds of listeners.
