An extraordinary sonic experience.

“Memory in Motion: Percussion in Surround” was a research project developed to examine how percussionists memorize musical actions within ensembles. As part of this research, director Aiyun Huang commissioned new works to compliment selected existing repertoire. Zihua Tan wrote Sorites to compliment Iannis Xenakis’s Persephassa and alcides lanza wrote mnais mnemes to compliment his own earlier composition sensor VI. In both cases, the composers were asked to use the identical setup and notational system as that of the existing works. By sharing this common DNA, these unique compositions synergistically flow together to form an unusually powerful listening experience.

Persephassa is a classic of the percussion repertoire, for six spatialised percussionists surrounding the audience. This, along with Tan’s Sorites, makes for extraordinary listening in surround, with the listener placed in the centre of the circular ensemble as acoustic sounds often ricochet or spin around the listener. The recording on this Mode release accurately places each percussionist in the soundstage (in the stereo version as well as the surround).

Contrastingly, Malaysian-born Zihua Tan’s Sorites is full of mystery. Its orchestration of grainy-sounding brush strokes not only softens the attacks, but also blurs the boundaries between different sounds, between one performer and another.

Mâche’s Aera is also for six percussionists. Using tuned gongs, vibraphones, marimbas, tubular bells, and timpani as the main colours in this 20-minute work, Mâche directs our ears to hear the inner resonance of these instruments and how the timbres and harmonies mingle and evolve when combinations of instruments shift.

lanza’s two works are scored for percussion quartet. sensor VI was inspired by the first moon-landing by the Apollo astronauts in 1969. lanza chose to reference the devices that sensed and transmitted the astronauts’ life-signs through space to technicians on the ground, and the relation these instruments have to the body’s sense organs.

His mnais mnemes draws formal and textural inspiration from freely-derived characteristics of the mnais mneme, a unique dragonfly found in China – its very elongated cylindrical body contrasts strongly with its large head and enormous glassy spherical eyes.
