First up is the fifth edition of USINA, which returns on 30 May 2026. The one day open air festival will once again transform the former industrial NeiSchmelz site into a vibrant space for music, performances, workshops and family friendly activities.
Designed as a festival that blends culture with heritage, USINA invites visitors to explore the historic site while taking part in a diverse programme of events.
Among the musical highlights this year is a headline set from German indie band Giant Rooks, who previously played in Dudelange earlier in their career. Speaking at the announcement, opderschmelz director John Rech said the organisers were delighted to welcome the band back.
“We are really happy to welcome back Giant Rooks”, said John Rech, Director of Opdershmelz, “They played here a few years ago just before they became so well known and started filling arenas across Europe.”
The festival will also feature performances from Chartreuse and Luxembourg’s Low Density Corporation, while other stages and spaces across the site will host DJs, workshops, street performers and family entertainment.
Visitors will be able to explore several historic areas within the NeiSchmelz complex, including the Vestiaires, the Wagonnage building, the Pomhouse and the water tower, each hosting different parts of the programme.
USINA is organised in collaboration with a wide network of cultural partners including Opderschmelz, den Atelier, de Gudde Wellen, Bombyx, CEPA, CNA, CNCI, DKollektiv, Jugendhaus, Pipapo and VEWA, highlighting the strong collaborative spirit behind the event.
With street artists, workshops, a fairground and food stands alongside the music programme, the festival continues to position itself as a day long celebration designed for audiences of all ages.
Earlier in the spring, Dudelange will also host a milestone edition of the Zeltik Festival, which celebrates its 30th anniversary from 12 to 15 March 2026.
Over the past three decades, the festival has grown into one of the most important Celtic music events in the region, regularly attracting fans from across Luxembourg and neighbouring countries.
“Reaching our 30th edition is more than a numerical milestone. It reflects decades of artistry, friendship and Celtic culture thriving here in Dudelange,” said John Rech.
The anniversary programme brings together a wide range of international artists, including Carlos Núñez, Red Hot Chilli Pipers, Skerryvore, The Celtic Social Club, Curly Strings, Ryan Young, Andrew Strong and Canadian roots band The Paperboys.
Concerts will take place across several venues in the city. The festival opens with the traditional Zeltik Prelude concerts in St Martin Church, before moving to the main stages at the CCRD opderschmelz. Late night sessions and informal performances will continue at the Kantin brewery, where musicians from the line up often join spontaneous jam sessions after the main concerts.
The format allows audiences to experience Celtic music in different settings, from intimate acoustic performances to high energy festival shows.
Together, the two festivals illustrate the breadth of Dudelange’s cultural programme, combining international touring acts, local artists and community partners in events that highlight both music and the city’s industrial heritage.
With USINA transforming the NeiSchmelz site into a creative playground in May and Zeltik celebrating three decades of Celtic music in March, 2026 is shaping up to be another lively year for culture in Dudelange.
