Utopia is the latest project from Teodor Currentzis, whose home ensemble has faced scrutiny over its ties to Russian state funding.HAMBURG, Germany — After Claude Debussy heard a young Igor Stravinsky’s “Firebird,” he was said to have quipped, “One has to start somewhere.”That start turned out to be auspicious. And Utopia — a new ensemble that has assembled some top performers from groups throughout Europe and abroad — has similar potential. It debuted this week, with a slight but superbly executed program of, as it happens, “The Firebird” and works by Ravel that it is currently touring, with a stop at the Laeiszhalle here on Wednesday evening.Utopia’s name inspires eye rolls; but its sound, awe. Tensions like that always seems to attach themselves to its founder and conductor, Teodor Currentzis, who often appears to serve himself more than music yet at the same time reveals what can feel like a previously veiled truth.His already complicated artistry has been complicated further since the war in Ukraine began. Currentzis was born in Greece but has long been based in Russia, where he was given citizenship by presidential decree in 2014. The invasion brought fresh scrutiny to his ensemble there, MusicAeterna, and its funding from the state-owned VTB Bank. Currentzis, for his part, has been silent, caught an irreconcilable position between Russia and the West. Members of MusicAeterna, however, have been seen on social media championing the invasion.Some presenters in Europe have canceled MusicAeterna’s or Currentzis’ engagements over the war — most recently, the Philharmonie in Cologne, Germany this week — while others have stood by them, including the mighty Salzburg Festival in Austria.When the creation of Utopia was announced in August, its rollout — seeking little press, and with only brief tours of one program at a time — came off as a rushed reaction to MusicAeterna’s troubles. After all, it was billed as an independent orchestra with independent (a euphemism for Western) funding. But the ensemble has been in development for several years.The State of the WarRussia’s Retreat: After significant gains in eastern cities like Lyman, Ukraine is pushing farther into Russian-held territory in the south, expanding its campaign as Moscow struggles to mount a response and hold the line. The Ukrainian victories came as President Vladimir V. Putin of Russia illegally annexed four regions where fighting is raging.Dugina Assassination: U.S. intelligence agencies believe parts of the Ukrainian government authorized the car bomb attack near Moscow in August that killed Daria Dugina, the daughter of a prominent Russian nationalist. American officials said they were not aware of the plan ahead of time and that they had admonished Ukraine over it.Oil Supply Cuts: Saudi Arabia and Russia, acting as leaders of the OPEC Plus energy cartel, agreed to a large production cut in a bid to raise prices, countering efforts by the United States and Europe to constrain the oil revenue Moscow is using to pay for its war in Ukraine.Putin’s Nuclear Threats: For the first time since the Cuban Missile Crisis in 1962, top Russian leaders are making explicit nuclear threats and officials in Washington are gaming out scenarios should Mr. Putin decide to use a tactical nuclear weapon.Currentzis could have more control over the story of Utopia if he weren’t so reticent because of the war. Then, he might be able to offer a stronger argument for the group’s existence than what has been advertised: simply to bring together “the best musicians from all around the world” for the web3-like purpose of decentralizing classical music.That said, there is undeniable talent among Utopia’s ranks. Sure, the concertmaster on Wednesday was Olga Volkova, who holds the same post in MusicAeterna, but elsewhere there were ambassadors from the Staatskapelle Berlin, the Mahler Chamber Orchestra and the Paris Opera; plenty of players born in Europe, but also ones from Australia, Asia and the Americas.With little rehearsal time, they gave their first concert in Luxembourg on Tuesday. After Hamburg comes Vienna, then Berlin, where vast swaths of the Philharmonie remain unsold. That was not the case on Tuesday at the more intimate Laeiszhalle, which was nearly full with a warmly receptive audience. Outside there was nary a protester, as there have been at the Russian soprano Anna Netrebko’s recent recitals, and inside Currentzis was greeted with cheers surpassed by only the riotous applause that followed each piece.It’s not hard to see why. This was an evening that never sagged or lacked in interest, even if Currentzis’ style tipped toward the profane. He relished extremes, with hyperbolic readings of the scores that you could say reflect a lack of trust or taste — but that you could also say are riveting from start to finish. Love or hate them, his performances make people truly care about music.If there were doubts that this pickup group wasn’t ready for the public, they were dispelled at the sound of the players’ sharp, decisive articulations and unison string downbows in the Stravinsky — his 1945 version of the “Firebird” suite — or their unwavering precision in the encore, Ravel’s “Boléro,” which on Wednesday began so softly, its patient, extended crescendo had the feel of a traveling band entering the scene from afar then boisterously announcing itself.On the program were three ballet scores, and Currentzis treated them with fitting sensuality and freedom. His Stravinsky breathed fire while also luxuriating in the winding tendrils of a flame. Ravel’s second suite from “Daphnis et Chloé” blossomed organically from a wispy opening’s gentle enchantment to a densely textured tableau that, even then, refrained from giving away too much too soon. But when the climax came, it was so powerful that I felt the nudging vibration of my watch warning me that the sound had pushed past 90 decibels.Throughout, the Utopia players were visibly pleased, and united. During Ravel’s “La Valse,” Currentzis didn’t keep time so much as swing his arms broadly from right to left and back again, yet the orchestra maintained controlled instability in this affectionate but darkly ambiguous tribute to Johann Strauss II and his symphonic treatments of Vienna’s signature dance.Ravel nearly named the piece after that city, with the German-language working title of “Wien.” Currentzis’ interpretation was largely one of entropy, but it also had transporting, whirlwind glimpses of a joyous ballroom. Those moments were a painful reminder of his current relationship with Vienna, where Utopia is welcome but MusicAeterna is not.These days, that kind of bitter aftertaste accompanies all of Currentzis’ performances, both the good and the bad — certainly on Wednesday, and who knows for how long.UtopiaPerformed on Wednesday at the Laeiszhalle, Hamburg, Germany.
