21st Century (2013). "For many centuries, large stone figures have brought up more questions than answers about the life of the ancient times in which they were created. Monolith for bass trombone explores and in some cases fantasizes one of those theories. In the piece, the bass trombone represents the large mysterious figure and gives insight to what it has seen over its many centuries of standing watch."
This piece was commissioned by and dedicated to Jose Leonardo Leon to be premiered at the 2013 National Trombone Week festival in Aguascalientes, Mexico. - Alejandro Guardia, Jr.
