HAUSER was four years old when a cello stopped him cold. It was a radio broadcast of The Swan, the most famous cello piece ever written, and the sound reached him in a way nothing else had. More than two decades later, standing on a stage in Sofia for the first time as a solo artist, that four-year-old’s obsession filled an entire arena with something between a classical concert, a tango night, and a rock spectacle that never once let the audience sit still.
From isolated kid to cello rebel
HAUSER has never hidden the cost of his gift. While other children played football and went out with friends, he was alone with his instrument, running scales and attending competitions, building the classical foundation that would later hold everything else up. ‘My career originates from classical music, dedicated rehearsals, discipline, sacrifice,’ he told the Sofia crowd, and the words carried the weight of someone who had lived them. For 25 years the classical world shaped him. It also caged him. Teachers pressed norms onto a personality that was always too large for a recital hall. By high school he was already performing with the energy of a rock concert, and the academics were already rolling their eyes. That tension eventually cracked open into Two Cellos, a decade-long run selling out arenas and proving, as he put it, that a cello can rock harder than any rock band. Sofia was the next chapter: the first solo concert in the city, and he said clearly he hoped it would not be the last.
A night built in movements, not setlists
The concert moved through carefully announced territories. The opening set was slow and romantic, classical in texture, and HAUSER warned the crowd with a grin not to fall asleep because things were about to get ‘completely crazy.’ They did. A tango section had him calling for water backstage afterward, joking that his leg hurt even though he had not danced. A waltz followed, and he invited anyone with a partner to simply get up and use the floor. A violinist named Carolyn Campbell drew her own standing ovation during the cinematic section, which HAUSER framed with a conviction that movie soundtracks are ‘modern-day classics in the deepest evolution of classical beauty.’ A saxophonist named Zie was introduced for the sensual stretch of the program, instructed warmly to ‘play for the ladies.’ The Latin section brought the arena fully to its feet, and the brass players he called Aon and Zali anchored the ensemble introductions that capped the main set.
The closing movement turned personal. HAUSER dimmed the entire arena and asked everyone to raise phones, lighters, and candles. The hall became, in his words, a sky full of stars. He chose Hallelujah as the final song, the one he called his absolute favorite, and he said he would remember Sofia forever.
The project that no other artist had tried
In between the dance sections, HAUSER laid out the ambition behind the most unusual part of the night. He described a project he called Music Unites the World: a decision to play one song from every single country on earth, covering every nation through the sound of a single cello. ‘I decided to do something that no other artist in history has ever done,’ he said, and the Sofia crowd heard a preview of it, a musical journey across cultures with no borders and no rules imposed on the repertoire.
The cello, left alone on the stage
After the encores ended and the arena began to empty, the instrument that started everything when a four-year-old heard it on the radio remained at the center of the stage. HAUSER had described its shape as resembling a female body and its sound as needing no translation in any country he had ever played. The cello asked for nothing further.
HAUSER told Sofia he would remember the night forever, then walked off the stage he had promised to return to.
