A Sound map Of The Hudson River (Lovely, 1990), composed in 1982, is a field recording of natural sounds and human voices along the Hudson river.

Sinopah (XI, 1998), a split album with Ruth Anderson, contains Lockwood's 46-minute World Rhythms (1975), a live improvisation that broadcasts natural sounds, from volcanic eruptions to earthquakes to geysers to bonfires to waves to human breathing. The continuum thus spans the dimensions of the human experience.
The album also contains Ruth Anderson's 23-minute Come Out Of Your Sleep (1997).

Breaking the Surface (Lovely Music, 1999) contains Duende and Delta Run (1982), one of her most moving pieces.

Lockwood has also composed Shapeshifter (1996), the microtonal concerto Western Spaces (1995) for flutes, zoomoozoophone and percussion, and Tongues Of Fire Tongues of Silk (1997) for eight sopranos and percussion.

Early Works 1967-82 (EM Records, 2007) contains the LP The Glass World (Tangent, 1970) and the 19-minute Tiger Balm (1970).

Thousand Year Dreaming/ Floating World (Pogus, 2007) collects the 35-minute electroacoustic piece Floating World (1999), created in studio from "spiritual" field recordings by her friends, and the 43-minute four-movement suite Thousand Year Dreaming (1991) for conch shell, trombone, multiple didjeridus, oboe, English horn, vocals (Annea Lockwood herself), clarinet and percussion, her sublime exercise in slo-motion subliminal glissandi and microtones bordering on both post-classical chamber music and creative jazz music. The languid and funereal timbres of trombones and didjeridoos sound like coyotes barking at the moon in the first movement. The wailing horns permeate the second movement at a volume that is barely audible, their black and white tapestry wrapped onto itself like a Moebius strip. The third movement increases the sense of musical alienation by staging a subdued melodic line in a swamp of fluttering patterns. The fourth movement continues to evolve the mono-dimensional tapestry with the clarinet's Stravinsky-ian motif, the didjeridoo's massive raga-like vibrations, the trombone's controlled deflagrations. The piece closes with a few anguished notes by the clarinet after a cryptic burst of polyphony.

Floating World (1999) belongs to a different genre of music altogether, a collage of electronically manipulated sounds of nature.

The triple-disc A Sound Map of the Danube (2008) is a 162-minute reevocation of life along the Danube via field recordings and interviews with ordinary people. Hence the journey (in space and time) begins with Bregquelle To Immendingen for German spoken-word (multiple men), running water and birds, especially majestic running water. Domesticated animals enter the picture in Fridingen To Ulm, then the water takes over again, but this time in a duet with church bells. Lockwood seems to complicate the picture a bit at the time, as the 14-minute Lauingen To Weltenburg is even less linear and more varied (people, water, animals, churches). Passau To Jochenstein Dam focuses on the water again, with the voice and church bells simply setting the stage for the final roaring crescendo of water. The problem, of course, is that there is only so much one can do with these elements. Therefore the 16-minute Inzell To Traismauer sounds uneventful and the 13-minute Donauwirt To Samor¡n since they simply recycle sounds that were already in the previous pieces (unless your ear is really sophisticated). A steam train engine (a train?) successfully lifts Orth To Haslau from the routine of water sounds. Esztergom To Keselyus opts for calmer waters and invisible sounds (perhaps of people nearby). The 15-minute Batina To Vukovar evokes one of the most pastoral vignettes before indulging in the usual loud gurgling. The 15-minute Backo Novo Selo To Dobra is another rural vignette. The 17-minute Kazan Gorges To Tutrakan invests more interviews, the voices gracefully blended with the natural sounds. Popina To Rasova finally explores more of the "other" sounds, sounds that are difficult to interpret and constitute the subconscious of life along a river. The 19-minute Nufaru To The Black Sea reaches the sea, and we hear the waves replacing the usual flow. This is all evocative and charming. One only wonders if it could have been edited down to a less sprawling dimension.

In Our Name (2012) collects Jitterbug (2007) for six-channel tape, a mixer and two live performers; In Our Name (2010) for voice, cello, and pre-recorded sound on tape; and Thirst (2008), a four-channel electro-acoustic work.

Her "Piano Transplants" performances include "Piano Burning" (1968), which simply consists in setting a piano on fire, "Piano Drowning" (1972), etc. "Piano Garden" (1969) is a piece that will take centuries to complete for half-interred pianos surrounded by fast-growing vegetation. The score is: "Plant fast growing trees and creepers around the pianos... leave the pianos there forever."

Ground Of Being (Recital, 2014) collects works of musique concrete from 1996-2013, notably the 16-minute Ear-Walking Woman, initially a flow of deformed/defaced sounds of animals with anguished or comic overtones, but then it turns to noises that evoke a metalworker's workshop; and the 19-minute Ground Of Being, which is the most complex multi-stage collage: deep cavernous ambience, droning emptiness, sounds of objects dropping to the floor, a barking dog, human voices, watery hisses, ominous rumbles... the sibilant and the rumbling fighting for supremacy... then suddenly an incursion by scratching and throbbing noises... back to the hissing emptiness. Not her most profound or coherent music, but rather a display of studio mastery.

Tiger Balm/ Amazonia Dreaming/ Immersion (Black Truffle, 2017) collects three compositions: the 19-minute Tiger Balm (originally released in 1970), Amazonia Dreaming (1987), and Immersion (1998).

Tiger Balm (1977) contains an 80-minute version of the piece.

Becoming Air/ Into The Vanishing Point (Black Truffle, 2021) contains Becoming Air (2018), developed with and performed by trumpeter Nate Wooley, and Into the Vanishing Point (2019), a collaborative with percussion quartet Yarn/Wire.

Tete-À-tete (2023) collects unreleased archival and new works by Ruth Anderson and Annea Lockwood (her widow).

On Fractured Ground / Skin Resonance (Black Truffle, 2025) contains two pieces: On Fractured Ground , a collaboration with Pedro Rebelo and Georgios Varoutsos for the film soundtrack for "History of the Present" (2023), and a collaboration with Vanessa Tomlinson, Skin Resonance.

The Piano Works (Unsounds, 2025) was performed by Xenia Pestova Bennett.
