Double Trouble: Duets at Grond
2025-11-20 20:00 - 21:30 (Europe/Amsterdam)
A new series of duet performances by some of Amsterdam’s best musicians. Curated by Grond member David Mitchell, the new series will put together pairs of musicians for new and unexpected encounters, showing different approaches to the same instrument or unusual combinations of instruments, all with a common aim: to take musicians out of their comfort zone. For the first edition we put together two electric guitarists with very different approaches: Theo Holsheimer has previously performed at Grond with Cilice Orchestra, his project that puts together the power of metal with intricate arrangements for jazz and classical musicians; David Mitchell has a background in modern jazz and the classical traditions of Central Asia, and works with long form loops to create complex layered improvisations. Thursday 20 November at 8pm, tickets 10Euros/7 Euros (concessions).

Friday 21 November, TEMPERATURA presents the latest edition of the Kleefstra brothers’ poetry-and-music project, IT DEEL IV. In this edition, Romke and Jan Kleefstra collaborate with the cello player Joana Guerra, and the violin player Maria do Mar. The same evening, a solo live-electronics performance by Orphax, aka Sietse van Erve.

• IT DEEL IV | Joana Guerra, Maria do Mar, Romke Kleefstra, Jan Kleefstra •
Poetry and music in an annually changing Frisian-international ensemble — that’s IT DEEL, a residency project by the Kleefstra brothers. Last summer, the Kleefstras invited cellist Joana Guerra and violinist Maria do Mar for a week-long creative residency at a special location: the Thomas Church in Katlijk. IT DEEL IV is out on vinyl LP on Moving Furniture Records. As part of their Dutch concert tour, they will make a stop at GROND to present their album in the Amsterdam audience.
The central theme running through all IT DEEL collaborations: the relationship between humans and nature, in all its beauty and complexity. It’s not a light topic, but one that is universal and deeply connecting. Each year, it’s remarkable to witness what has emerged from the Fryske grûn (Frisian soil) in the dialogue between the Kleefstras and their European guest musicians. Missed earlier editions? This is your last chance: IT DEEL IV is the final instalment of the project. Already a long-time follower? Excellent—we’ll see you there!
• Orphax •
Amsterdam based musician and trained drummer Sietse van Erve (Orphax) was introduced to electronic music in the early nineties. After playing around with tracker software for a couple of years, he eventually recorded his first more serious attempts of music with beats and melodies in 1998, though soon lost interest in both these.
He started researching new sounds and new ways of working – always with an organic touch, often incorporating sounds that would be regarded by others as errors or mistakes. Considering life isn’t without errors either. During this search, he found his way into drone and microtonal music. As a result in his most recent work, time and spatiality become more important factors. The goal of the music is for the listener to lose the sense of time and place.
Live, this is combined with room for improvisation. This way of working results often in an organic form of drone and minimal music.

Tuesday 25 November, TEMPERATURA presents an acoustic popup event with selected compositions and improvisation sets by Leah Asher, Maya Bennardo, and Christian Streit Smith.
Violinist/violist, composer, and visual artist Leah Asher is an avid performer of contemporary music and creator of new artistic works. Leah is the executive director and violinist of The Rhythm Method string quartet and co-creator of performance art duo Meaningless Work with Nicolee Kuester. Leah regularly performs with New York-based ensembles such as International Contemporary Ensemble, Talea Ensemble, and S.E.M. Ensemble. She formerly served as solo violist of NOSO Sinfoniettaen and co-principal viola of the Arctic Philharmonic. As a composer, Leah has been commissioned by ensembles including andPlay, Chartreuse, Periapsis, NorthArc Percussion Group, The Great Learning Orchestra, and Ensemble Hybrid. She serves on faculty at Lake George Composer’s Institute, the Composers Conference, and the Lucerne Festival Academy, and has conducted many residencies at universities including NYU, Columbia University, Berklee College of Music, Hunter College, and BGSU. Recent releases include Leah’s solo album ‘Retreat into Afters’ on SCRIPTS records, The Rhythm Method’s ‘Pastorale’ on New Focus Recordings, and The Rhythm Method’s ‘Seaglass’ on Gold Bolus Recordings. Leah joined the faculty of Manhattan School of Music in 2022.
Maya Bennardo is an active performer and composer living in Stockholm, Sweden. Maya is interested in opening the dialogue and blurring the boundaries between composers and performers, and is devoted to performing music of the present. She is a founding member of the violin/viola duo andPlay, described by I Care If You Listen as “enthusiastic champions for new music and collaboration.” She performs new and traditional repertoire for violin and piano with pianist Karl Larson in their Bennardo-Larson Duo and is a former member of the internationally renowned Mivos Quartet. Maya’s compositions are characterized by slow, unfolding timbral movements–exploring the co-existence of pitch and noise. Her compositions have grown naturally out of her improvisational practice on the violin, and the two continue to inform each other.
Christian Streit Smith (USA/NL) is a percussionist based in The Hague. He performs experimental music (composed and improvised), in many different constellations from solo to large ensemble to theater. In addition to his work as a musician, he works part time as a landscaper.
