Stuart O'Neil has written a new work entitled "Machinery" in 4 movements for 6-part Trombone ensemble and Percussion. Below is the composer's explanation of his exciting and dramatic work."The four pieces in this collection are written for 6-part trombone ensemble and accompanying percussion; they may be performed together or individually. Each piece is a study in the trombone’s distinct glissando capability and should be approached in a relatively aggressive, but not overly serious, manner: concert music, but with considerable jazz-rock influence, especially in regards to rhythm and dynamics. The pieces are similar, but each has its own character."1. Machine is a well-oiled, highly-functioning machine, with all parts efficiently working together.2. Rush Hour is a hectic, busy traffic scene, but somewhat cartoon-like.3. Suspension Bridge is strong metal under extreme stress, straining but not breaking.4. Assembly Line is a factory conveyor belt: loud, busy, with lots of heavy machinery.This 10 minute work is appropriate for advanced performers.
