ThunderGrass: summoning a storm of tightly wound improvisations in a whirlwind of sound. Howling horns Ros Jones and Gemma Horbury meet rumbling drum ‘n’ bass Nat Grant and Miranda Hill as the squall approaches.

We acknowledge Australia's Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live, and give respect to their Elders both past and present.



New instrumental quartet ThunderGrass launched at La Mama Musica in October 2019. Focusing on long form improvisation and taking inspiration from The Necks, the Art Orchestra of Chicago, and Sun Ra Arkestra amongst others, they move freely between groove based riffs and abstract soundscapes. The ensemble members' long collaboration history with Adam Simmons Creative Music Ensemble, Bombay Royale, Octave Pussy, The Women, and many more provides a shared language to create a tightly woven sound. Howling horns Ros Jones (trombone) and Gemma Horbury (trumpet) meet rumbling drum ‘n’ bass Nat Grant and Miranda Hill as the squall approaches.




Nat Grant is a composer and sound artist working across live performance, installation, and sound design: a percussionist and drummer who creates devised, notated, electroacoustic, and improvised works for recordings and live performance.

Nat has created original music for theatre, dance, film, and live art, holds a PhD in composition from the Victorian College of the Arts, and in 2018 received the Age Music Victoria award for best Experimental/Avant-Garde Act.

Nat has taught instrumental music to people of all ages and is invested in creating community around music and sound making.


Double Bass

Miranda is a double bassist, G-violonist, producer, and educator with a diverse musical career, specialising in historically informed performance, contemporary classical music, improvisation, electro-acoustic collaborations, and an unexpected side-career in community protest marching bands.

Miranda is Artistic Director of Homophonic! the queerest chamber music series in existence; a core member of Genesis Baroque, BOLT ensemble, Arcko Symphonic EnsembleMelbourne Baroque Orchestra; one half of Octave Pussy electro-acoustic drum’n’bass duo, and one quarter of art music quartet Thundergrass.




Seen on stages across the world, Ros Jones has performed in some of Melbourne's most exciting bands including the Bombay Royale, Vulgargrad, Hoodoo Mayhem Brass Band and more. If the horn line-up is killer, odds are she's in the mix.



Award-winning trumpeter Gemma Horbury brings an ever-evolving skill set to the stage: going beyond brass to incorporate visuals, vocals and hip hop MC-ing in charismatic, genre-defying performances. She has performed internationally in Europe, the UK and Asia; and at top Australian festivals including The Big Day Out, Woodford Folk Festival, The Falls Festival and Melbourne’s International Jazz and Comedy Festivals.
Gemma is known for her unique sound and on-stage presence whether playing jazz, classical, world music, contemporary or experimental styles. Her work shifts between technological innovation and tradition yet is underpinned by deep connections to sustainability and developing community capacity through the arts.
