Experimental music festivals are where drone music gets the conditions it needs and rarely finds elsewhere: long durations, quiet rooms, large sound systems and audiences prepared to sit still. A handful of events in Europe and the United States have built reputations as the places where sustained, slow and minimalist work is programmed alongside noise, electronics and contemporary composition. This guide covers six of them. Every date and location below was checked against the festival’s own announcements or against recent music press, with the situation current as of 6 November 2026. Festival programs change, so the sources linked in each section are the place to confirm details before booking travel.
CTM, Berlin
The Berlin festival CTM describes itself as an independent, non-profit initiative that emerged in 1999 from the city’s DIY and club scenes and builds each year’s program around a theme, with guest curators and researchers. Its 2026 activities spread across 13 venues. The same page says it focuses on music and sound that resist easy categorization, which is the background to the CTM Festival name that drone listeners may already know from releases and lineups.
Its 28th edition ran from 22 to 31 January 2027 in Berlin. Running ten days in midwinter, CTM is the only event in this guide that takes place in January, which makes it the first stop of the festival year.
Unsound, Kraków and beyond
Unsound is rooted in Kraków but now works as a traveling network. The 2026 edition was titled Soft Power, and the festival ran in Warsaw from 2 to 6 October, followed by an “Unsound Train” on 7 October and Kraków from 8 to 11 October. The same announcement explains that shows are not repeated between the two cities, so a full pass means following the festival across Poland. It frames the theme as a question about softness and power under authoritarian pressure, AI and algorithmic control, and it states that the edition builds on the 2024 theme, Noise.
The Unsound Festival is a useful example of how a festival can use a theme as an editorial tool: in 2026 the Soft Power theme organizes both the discourse program and a music program that examines intimacy, vulnerability, authority, pressure, volume and scale. For listeners, the October timing makes it a natural bookend to the festival year, and the Kraków dates have now passed, so the next edition is the one to watch.
Sonic Acts, Amsterdam
Sonic Acts differs from the others because it behaves more like an arts organization than a weekend event. According to the Amsterdam city culture guide, it began in 1994, focuses on art, science, technology and music, and grew into a biennial. The 2026 edition, titled Melted for Love, ran from 5 February to 29 March 2026, with an intensive festival weekend from 26 February to 1 March. The main exhibition was spread across venues including W139 and Arti et Amicitiae, and the full program used between fifteen and twenty places in the city.
That structure suits slow listening. An exhibition that runs for about seven weeks allows repeated visits, which matters for installation-based sound art and for pieces designed to be encountered at length. Because the event is biennial, 2026 has already closed; the Sonic Acts glossary entry gives background while the next edition takes shape.
Le Guess Who?, Utrecht
Le Guess Who? celebrated its 20th anniversary with an edition in Utrecht from 5 to 8 November 2026. Its distinguishing format is the guest curator. For that edition the curators were the poet aja monet, the sound artist KMRU, Los Thuthanaka and Tropical Fuck Storm, each of whom programmed a portion of the lineup.
The most relevant item for drone listeners is KMRU’s WAI8, described in the festival’s announcement as an eight-hour durational performance with nine performers that uses drones, noise and silence to stretch and fracture time. The curator model is the point to note for planning: each year’s lineup reflects the taste of the invited curators, so a future edition can look very different from this one.
Big Ears, Knoxville
Big Ears is the American festival with the clearest line to minimalism and drone. The next edition is scheduled for 1 to 4 April 2027 in Knoxville, Tennessee. The event’s history supports the reputation. According to its Wikipedia entry, Big Ears was founded in 2009; Terry Riley served as its first Artist in Residence in 2010, Steve Reich curated the 2014 edition, and Sunn O))) performed in 2016. The same entry lists Philip Glass and Pauline Oliveros among the performers at the first edition in 2009, and records that the festival became a nonprofit in 2016.
Those names connect directly to the tradition covered in the glossary: Terry Riley and Sunn O))) sit at two different poles of sustained sound, one in pulse-based minimalism and the other in amplified, slow doom. More recent organ and just-intonation work, including that of Kali Malone, is covered in the pipe organ drone revival. The festival’s website is the place to check passes and the 2027 lineup.
Supersonic, Birmingham
Supersonic is the most precarious of the six, and its status needs the most careful reading. In January 2026 The Quietus reported that the festival would hold a stripped-back edition on 25 and 26 April 2026, moved from its usual late-August slot. The organizers said the earlier date gave them time to plan beyond 2026, and they cited years of “battling against rapid gentrification” in Digbeth, the Birmingham district where the festival has been based. The options they described included new venue partnerships, a move elsewhere, or reinventing the format.
No 2027 plans were confirmed in that report. A reader hoping to attend should therefore treat Supersonic as active but unscheduled until the organizers publish new dates. The dates for any later edition, and whether it stays in Digbeth, are the open questions to follow.
Choosing among experimental music festivals
For anyone planning a year of listening, the calendar runs roughly as follows: CTM in late January, Big Ears in early April, Unsound in October and Le Guess Who? in early November. Sonic Acts returns every second year, its 2026 edition having run from February to March, and Supersonic’s next dates are still to be confirmed. Dates change from year to year, so each festival’s own site is the reference before booking. The six events answer different needs. CTM suits listeners who want theory and club culture in the same week, in January. Unsound is the pick for a theme-driven program in Poland in autumn. Sonic Acts rewards patience and gallery visits, but only every second year. Le Guess Who? offers the widest stylistic spread and a curator model that changes the character of the lineup each November. Big Ears gives the strongest connection to American minimalism, in spring. Supersonic remains the small, independent option whose future depends on announcements still to come.
For a first visit, preparation matters more than the choice of festival. Long sets reward a quiet approach, and how to listen to drone music outlines one. The labels that release much of the music heard at these events are covered in drone music record labels, a useful companion when a festival name leads to a new artist.
