Her favorite instrument since the 1970s was the ARP 2500 synthesizer.
Her performances became famous for endurance pieces.
Geelriandre - Arthesis (Fringes, 2003 - Important, 2018) collects
two droning pieces
composed before Radigue began to focus on feedback:
Geelriandre (1972),
for prepared piano and synthesizer,
that weaves together low-volume cricket-like noise and
ticking piano notes in a highly otherworldly manner,
the synth noise slowly evolving to become a galactic radio signal;
and
Arthesis (1973), a subminimal synthesizer rumble in motion
that slowly mutates into other moving sounds
until it becomes a wall clock striking the hour.
Adnos I-III (Table of the Elements, 2002), a new triloy composed between 1974 and 1982, is a monumental work of meticulously assembled electronic music
that implements slowly evolving drones. As variation only occurs over a
long period of time, this makes for hyper-deep listening.
The first part was composed independently of the second and third.
She performed in San Francisco in 1974 and was then introduced to
Tibetan Buddhism, which first inspired
Triptych (1978)
then the second (1980) and third (1981) parts of Adnos, and then
Songs Of Milarepa (1983),
Jetsun Mila (1986) and the "Trilogy of Death": Kyema (1988), Kailasha (1991) and Koume (1993).
L'Ile Re-Sonante (Shiiin, 2005) is a 55-minute composition dating from
2000.
The double-CD Chry-ptus (Schoolmap, 2007) collects
four versions of Chry-ptus.
The original version was revisited in 2001 and 2006.
Lappetites' Before The Libretto (Quecksilber, 2005) was a collaboration among Elaine Radigue (France), Kaffe Matthews (Britain), Ryoko Kuwajima (Japan), and Antye Greie-Fuchs (Germany), basically a multinational laptop quartet ranging in age from the 70-year old Radigue to the Japanese youth.
Vice Versa, etc.... (Important, 2009)
is a double-disc album curated by Manu Holterbach that includes one of Radigue's
earliest compositions and several "remixes" of sorts.
Radigue's piece for magnetic tape Viceversa (1970)
came with the instructions to be played back at any speed and at any duration
and either backwards or forwards.
The album contains the original Radigue-made tape and
a number of variations played backwards and at different speeds.
Jouet Electronique/Elemental I (Alga Marghen, 2011)
collects two early compositions for feedback, composed and recorded between 1967 and 1968:
the 12-minute Jouet Electronique (1967), that toys with purely electronic
sounds and produces elegant and calm variations,
and the four-movement Elemental I (1968), that employs
natural sounds as sources and produces much more varied and violent effects (one of the few compositions that is indeed musique concrete).
Elemental II (2005 - Recordings Of Sleaze Art, 2012) documents a 2004 live performance with Kasper Toeplitz.
She stopped writing for synthesized sound in 2001 and started collaborating with cellist Charles Curtis, bassoonist Dafne Vicente-Sandoval, harpist Rhodri Davies and tubist Robin Hayward.
Transamorem - Transmortem (Important, 2011) documents a 67-minute sound installation for synthesizer from 1974.
The ear-splitting hiss and the monotonous vibration destabilize each other
along the way, but the difference really requires extremely "deep" listening
to be appreciated.
Occam I (2011) for solo harp
(designed for cellist Charles Curtis, who had been collaborating with La Monte Young and Marina Zazeela since 1987)
began a new series, the "Occam Ocean" series, continued with
Occam II (2012) for violin,
Occam III (2012) for birnbyne,
Occam IV for viola,
Occam VI for synthesizer,
Occam River I for birnbyne and viola,
Occam Delta I for birnbyne violin, viola and harp,
Occam Delta II for bass clarinet, viola and harp,
Occam V for cello,
Occam VII for voice,
Occam VIII for cello,
Occam IX (2013),
Occam X for trumpet,
Occam XI for tuba,
Occam River II for violin and cello.
Solo pieces are titled "Occam", duo pieces "River" and larger ensemble pieces "Delta".
Feedback Works (2012) collects three sound installations:
Usral (1969),
Omnht (1970),
and Stress Osaka (1970).
They are representative of her "musique sans fin" ("endless music") intended for ad libitum broadcast in a gallery or museum, ideal as an eternal soundtrack to an art exhibition.
Another example is
Labyrinthe Sonore (1970).
Opus 17 (2013) contains a five-movement piece performed at a happening in 1970, her last composition for feedback, and also the composition that interrupted her "Musique sans Fin" series.
Psi 847 (2013), originally composed in 1972, is one of her major works,
a hypnotic stream of ringing tolls that is dwarfed by a violent, shrill drone
over the course of more than 70 minutes of organic unfolding.
After abandoning electronic music,
Naldjorlak (2008), an hour-long piece for solo cello, composed in 2004, premiered in 2005 and recorded at a Paris chapel in 2006,
was her first entirely acoustic composition.
The piece was born out of discussions with the performer, cellist
Charles Curtis.
It was then expanded into a work for a chamber trio
(basset-horn players Carol Robinson and Bruno Martinez next to Curtis on cello),
first premiered in 2009,
as documented on
the triple-disc
Naldjorlak I II III (2013).
Octopus (Bocian, 2019) documents a collaboration with Helene Breschand and Kasper Toeplitz.
The "Occam" series consists of chamber works for which the score is replace by a discussion between composer and performer, the method experimented in
Naldjorlak.
The double-disc
Occam Ocean 1 (2017) contains
Occam River I (14:19),
Occam I (29:14),
Occam III (16:31),
Occam IV (21:11) and
Occam Delta II (25:03).
Occam Ocean 2 (2019) contains the 52-minute Occam Ocean (2015) for orchestra (five clarinets, three contrabasses, two euphoniums, three guitars, three percussionists, accordion, six saxophones, trombone, trumpet, tuba, two violas, violin and two cellos).
Occam Ocean 3 (2021) contains Occam River II (23:42), Occam VIII (20:34) and Occam Delta III (23:23).
Occam Ocean 4 (2021) contains:
Occam Delta XIX (24:15) for alto saxophone, viola da gamba and birbyne;
Occam XXII (17:34) for baritones; and
Occam River XXII (26:00) for alto saxophone and bass clarinet.
Occam XXV (2018) was performed at a pipe organ of a London church in 2018 by organist Frederic Blondy, her first composition for the pipe organ.
By 2021 there were 50 solo and ensemble pieces written for the "Occam Ocean" series.
