Two years after his first European club dates, Sombr returns in spring 2027 with his first arena tour. The You Are the Reason Tour opens at the Unity Arena outside Oslo on 8 May 2027 and plays 16 continental arena dates in three and a half weeks, including two nights at the LANXESS Arena in Cologne and two at the Ziggo Dome in Amsterdam, which closes the run on 1 June.
Ireland and Britain follow in June, with Malahide Castle near Dublin on 15 June, Belsonic in Belfast, Summer Sessions in Glasgow and five nights at The O2 in London. A last European date is booked at the I-Days festival in Milan on 14 July 2027.
Below you will find the confirmed dates, the venue guide, a night-by-night view of the tour and every European concert the archive holds for Sombr, from VEGA in Copenhagen in June 2025 to his first European festival summer in 2026.
The run starts in the north. After Oslo comes the Avicii Arena in Stockholm on 9 May, the Veikkaus Arena in Helsinki on 11 May and the Royal Arena in Copenhagen on 13 May. Hamburg's Barclays Arena (14 May) and the AFAS Dome in Antwerp (16 May) follow, then the Uber Arena in Berlin (18 May) and the O2 Arena in Prague (19 May).
Paris is on Saturday 22 May at the Accor Arena. The tour then plays two nights at the LANXESS Arena in Cologne (23 and 24 May), the Hallenstadion in Zurich (27 May), the Olympiahalle in Munich (28 May) and the Wiener Stadthalle in Vienna (29 May), before the two Ziggo Dome nights on 31 May and 1 June 2027.
Almost every country on the route had seen Sombr in a club, theatre or festival within the previous eighteen months. In Paris he went from the Bataclan in June 2025 to the Salle Pleyel in February 2026 and now the Accor Arena; in Cologne from the Carlswerk Victoria to the Palladium and now two LANXESS nights.
Tickets went on general sale on 4 September 2026, after presales on 2 and 3 September. No support acts had been named as of 5 October 2026.

Sombr's first European headline shows came in the summer of 2025, on The Late Nights & Young Romance Tour, which began in Dublin on 25 May. The continental dates in June took in Store VEGA in Copenhagen on 7 June, the Ancienne Belgique in Brussels, the Paradiso Tolhuistuin in Amsterdam, two nights at the Carlswerk Victoria in Cologne, SaSaZu in Prague, and two nights at the Bataclan in Paris on 22 and 23 June 2025.
By then "Back to Friends" and "Undressed" had gone viral and were climbing charts in several countries, and in July 2025 a second European leg was added for early 2026. It started at Annexet in Stockholm on 10 February 2026 and went through KB Hallen in Copenhagen, the Inselpark Arena in Hamburg, Forum Karlín in Prague, the Gasometer in Vienna, the Tonhalle in Munich and The Hall at Dübendorf near Zurich. That leg also took in Warsaw, Milan, Madrid and Barcelona, according to the tour's Wikipedia listing.
The French capital got two nights at the Salle Pleyel, on 27 February and 1 March 2026. AFAS Live in Amsterdam followed, then the Velodrom in Berlin on 4 March, the Palladium in Cologne on 5 March and the Ancienne Belgique on 6 March, before the leg ended at the 3Arena in Dublin. Shows on that run lasted about 17 songs.
In August 2026 Sombr played his first big European festival season: Syd for Solen in Copenhagen's Valbyparken on 13 August, Øya in Oslo on 14 August, Way Out West in Gothenburg on 15 August and Flow in Helsinki on 16 August, then Pukkelpop at Hasselt on 23 August and Rock en Seine at Saint-Cloud on 26 August. A show at the Olympiapark in Munich on 1 September 2026 closed the summer.
The table below lists 25 documented European concerts by Sombr between 2025 and 2026, with the most shows in Paris (4), Copenhagen (3), Cologne (3), Munich (2), Brussels (2), Prague (2). It is not exhaustive: it only includes documented shows.

Across the 15 most recent documented European concerts with a full song list (23 June 2025 to 1 September 2026), these are the songs that came up most often. Titles only — set lists change from night to night.
Sombr's European festival history is one summer long, but it is a full one: the Nordic weekend of Syd for Solen, Øya, Way Out West and Flow, then Pukkelpop and Rock en Seine in late August 2026. Festival sets ran to 11 to 14 songs.
In 2027 the festival-style dates are outdoor shows at Malahide Castle near Dublin (15 June), Belsonic in Belfast, Summer Sessions in Glasgow and the I-Days festival at the Ippodromo SNAI San Siro in Milan on 14 July.
Sombr is the stage name of Shane Michael Boose, born in New York City on 5 July 2005 and raised on the Lower East Side. He studied voice at LaGuardia High School but left in his junior year after his song "Caroline" took off in 2022. The name comes from his initials, SMB, and the mood he was in when he started.
He learned to produce on GarageBand and Logic Pro and still produces much of his own material. After "Caroline" went viral he signed with Warner Records in 2023 and released the EP In Another Life that September, followed by the single "Would've Been You".
In 2025 "Back to Friends" and "Undressed" exploded on TikTok and reached the top 20 of the Billboard Hot 100; "Undressed" topped the Irish chart and reached the UK top five. "We Never Dated" and "12 to 12" followed, and the debut album I Barely Know Her, released on 22 August 2025, reached the top ten in the UK and the United States. He won Best Alternative Video at the 2025 MTV VMAs and was nominated for Best New Artist at the Grammys.
"Homewrecker", released in February 2026, reached the UK and Irish top ten, and "My Body Isn't Ready" followed in June 2026. Sombr cites Jeff Buckley and Radiohead as his main influences.
| Album | Year | Chart peak |
|---|---|---|
| I Barely Know Her | 2025 | UK 10 |
The Netherlands caught on early. Sombr played the Paradiso Tolhuistuin in June 2025 and AFAS Live in early 2026, and the 2027 tour ends its continental arena run with two nights at the Ziggo Dome on 31 May and 1 June.
It is the only city apart from Cologne with two arena nights on the continent, and the last indoor show before the open-air dates in Ireland and the UK.
Paris is a good measure of how fast things moved. In June 2025 Sombr played two nights at the Bataclan. In February and March 2026 it was two nights at the Salle Pleyel. On 22 May 2027 he plays the Accor Arena, the largest indoor arena in the city.
Rock en Seine at Saint-Cloud on 26 August 2026 was his only French festival date in the archive.
Germany has four arena cities in 2027: Hamburg (14 May), Berlin (18 May), Cologne (23 and 24 May) and Munich (28 May). Cologne is the one that gets two nights, after two nights at the Carlswerk Victoria in June 2025 and the Palladium in March 2026.
Berlin moves from the Velodrom to the Uber Arena, and Munich from the Tonhalle to the Olympiahalle.
Ireland put Sombr at number one with "Undressed". His first European tour began in Dublin in May 2025 and the 2026 leg ended there at the 3Arena. In 2027 he plays Malahide Castle, an open-air site north of the city, on 15 June.
Milan's I-Days festival on 14 July 2027 is the last European date announced. It is a festival ticket, sold by the I-Days organisers.
The early 2026 shows ran to about 17 songs, built on I Barely Know Her: "undressed", "back to friends", "we never dated", "12 to 12", "would've been you", "i wish i knew how to quit you", "perfume", "do i ever cross your mind", "come closer", "crushing", "savior" and "caroline".
By the Munich show on 1 September 2026 the set included the 2026 singles "Homewrecker" and "My Body Isn't Ready", plus "under the mat" and "Potential", and ended with "back to friends" and "12 to 12". The arena show for 2027 has not been published.
Tickets have been on general sale since 4 September 2026, after presales on 2 and 3 September, through the official ticketing outlets of each country. The Milan date is sold as an I-Days festival ticket.
There is no public Sombr presale code; codes sold on social media are not genuine, and some unofficial "tour" websites have published invented dates. Only the venue and official outlets list the real ones. If your date is sold out, use the official resale service of the country concerned.
