Heather Lockie (@marshweedinthegarden) is an L.A.-based composer, performer, and painter who creates graphic score, soundscape, song, installation, improvisation, and through-composed works. Often using stringed instruments, voice, and found objects, Lockie’s work stretches from ensemble and solo performances to formal string arrangements for herself and for others’ music to realizing her own graphic scores in performance.  
 
Frequently drawing from whatever soundmaking devices are at hand - a string trio, close vocal harmonies, a penny whistle, live-processed field recording, an oven rack, a folk song, a bell - she has imagined a unique hybrid form where traditional song form can intentionally — or aleatorically — merge with abstract sound-painting expressions and organic sonic pathways. Her two solo albums under the moniker Marshweed (Point of Contact, 2025; Marshweed in the Garden, 2017) both employ such logic, presenting collections of music as wildly diverse as the experiences of a single day of life in Los Angeles. 
 
Lockie’s performances and residencies include Leonardo@Djerassi 2025 (Woodside, CA), Studio for Centrum (Port Townsend, WA), Hill House Residency (East Jordan, MI), Electro-Instrumental Music (STEIM, Amsterdam), PACT Zollverein (Essen, DE), and — in Los Angeles — Dog Star Festival, Machine Project, NEWTOWN (Pasadena Art Alliance) and the Society for the Activation of Social Space through Art and Sound (SASSAS), LA Film Forum, EARMEAL broadcast. Lockie performs with Marshweed as well as experimental duo Spiders with Kalashnikovs, rebetiko folk group Galamatas, and folk/pop Desert Magic. She has premiered graphic score pieces with Southland Ensemble and with Dog Star Festival. She also co-curates and co-produces experimental music concerts at the house venue Casa Berenice Recordings.
 
In addition to Marshweed, Lockie has played and toured with her other bands Listing Ship and Leather Hyman as well as with international artists including Ty Segall, Cory Hanson, OCS, Mikal Cronin, Fun., Spiritualized, Scott Wieland (STP), Arthur Lee/LOVE, Eels, and various independent bands. She has performed both her own music and as a backing musician to internationally-known artists in a wide variety of musical venues that reflect the diversity of her musical output, from DIY spaces such as backyard tree house shows to venues such as the Royal Albert Hall and Letterman, to Los Angeles County Museum of Art and Museum of Jurassic Technology.
 
She earned an MFA (Performer/Composer) from California Institute of the Arts, studying with Sara Roberts and Wolfgang Von Schweinitz. She earned a BA from Occidental College (Comparative Literature-French/English). In addition to making her own music, she runs a private music studio and works with various child orchestras in the LA basin.
