[Aug 28 – Sept 26] Ephemerospheres by Mike Bullock

Ephemerospheres is an installation of electroacoustic audio works for wave field synthesis speaker array. The system’s creator, Mike Bullock, is a composer and intermedia artist whose work centers on listening to the unique qualities of particular spaces, both while recording natural environments and while creating virtual ones with loudspeakers.

Bullock designed and built his wave field synthesis (WFS) speaker array as part of Ears In Space, an umbrella project that includes his work in spatial audio technology as well as environmental recording. He considers Ears In Space complementary to his artistic practice, operating in the overlap between his art and collaborations with other artists and researchers.

Wave field synthesis places virtual sound sources in real space with a high degree of precision, using dozens of small speakers in a linear array. A computer coordinates the firing of the loudspeakers to generate coherent wave fields in a two-dimensional space in front of the array. Unlike the much larger WFS arrays at arts institutions like EMPAC – where Bullock first worked with this technology – the Ears In Space WFS array is designed for intimate spaces, smaller galleries, and homes. The system is portable and modular, allowing for expansion and experimentation.

About the works in Ephemerospheres

Combining Bullock’s own compositions with those of a guest composer, Ephemerospheres will create a shifting audio ecology that adapts itself to the room and its occupants in the welcoming quiet of Nolan Park. Among the pieces in Ephemerospheres will be “Ultrasonisphere” (2020), the first piece conceived for the Ears In Space wave field synthesis array. It is composed primarily of the ultrasonic sounds used by bats for hunting and communication, along with other environmental and synthesized sounds.

Title(s) of works and durations

“Ultrasonisphere” 18 min.
“Hydrophonisphere/Various Divergences” 37 min. (includes optional single-channel video projection)
“Vernalities” 10 min.

“I have always witnessed [Bullock’s] restlessly energetic explorations with amazement… At this point, I never know what to expect from Mike’s records, except that they won’t sound like the previous one. [Mild Disappearances CD] is no exception. Think of the gravity-free improvisations of Keith Rowe, the inner-space depression meditations of Maurizio Bianchi, or perhaps… ah, forget it. It only sounds like Mike Bullock after all.” – Howard Stelzer, composer

“Listened to your LP Figures Without Ground – actually listened to it a few time recently – I just wish it would go on and on and on.” -Gen Ken Montgomery, artist

Praise for Listen to Winter, collaborative album by Hello@ (Bullock/Aubry):
”Listen to Winter is lovely, peaceful and a lovely mix of crunching snow, bells from France, bass and much more….what a treat….” – Annea Lockwood, composer,
