The Seven Wonders of the Ancient World is a piano concerto performed by a percussionist. It is the premier work for a new hybrid acoustic instrument, the "Radio-Drum-driven Disklavier", which allows the gestural vocabulary of a percussionist to speak with the voice of an acoustic grand piano. The sound of this new instrument is massive and grand, even monumental, giving a new sense to the word "pianistic", and is further extended by a unique ensemble of acoustic plucked string and percussion instruments. All sound is entirely acoustic and performed as it would be in a concert setting--there are no loudspeakers, electronic sound or over-dubbing. The work was released on CD in October, 1996 on the Well-Tempered productions label. Commissioned by a National Endowment for the Arts Collaborative Fellowship, it involved a collaboration between composer David A. Jaffe and percussionist Andrew Schloss. The two worked as Resident Artists at the Banff Centre for the Arts in 1992-1993, where they developed the new instrument and refined the solo part.
