El pájaro de fuego
Ferguson designed the Firebird and the Superbone. The Firebird was similar to a trumpet, but the valves were played with the left hand instead of the right, and a trombone-style slide was played with the right hand. Trumpeter Rajesh Mehta bought this trumpet while living in Amsterdam and played the Firebird from 1998 until 2011 when he had American trumpet maker George Schlub create the Orka-M Naga Phoenix trumpet for him. The Superbone was another hybrid instrument, a trombone with additional valves played with the left hand. Ferguson incorporated Indian instruments and influences in his music.
