Formed in May 2013, the band from Gyergyószentmiklós has maintained the same lineup and rapidly gained popularity. With their energetic, audience-centered performances, the Bagossy Brothers Company quickly became one of the most popular bands among Hungarians, first in Transylvania and later throughout the entire Carpathian Basin.

During their career, the band has released five studio albums, one symphonic concert album, one EP, and a special Christmas album. All of their albums have achieved multiple gold certifications, while their 2019 album Veled Utazom earned six-times platinum status, the highest album sales certification in Hungary. Their 2021 album Fordul a világ has reached four-times platinum. Alongside their music, their career has been accompanied by two books, a film, numerous music videos, and other materials.

In 2023, the band released two albums. After their fifth studio album Angyalok A Parkolóban was released in the summer, they followed up in December with a special Christmas album titled Ünnep, which features not only their own songs but also unique adaptations of church and folk songs characteristic of the Gyergyó Basin.

The band's career has been marked by numerous awards, including four Petőfi Music Awards (Acoustic Concert of the Year, Band of the Year, Music Video of the Year, and Performer of the Year for Norbi Bagossy) and two Fonogram Awards (Recording of the Year). They also won Transylvania's most prestigious music award, the title of Most Beautiful Transylvanian Hungarian Song.

In 2020, a public opinion survey conducted by the Due Media Research Network named them the most popular band in Hungary. In the same year, they became the only Hungarian band to appear on Spotify's annual TOP 10 list in both the band and song categories.

By now, the band has sold out all major concert venues in Hungary, including Europe's 7th largest indoor arena, the MVM Dome. 

After two years, the band is returning to the MVM Dome, where they previously celebrated their anniversary, and they are preparing another truly special concert.
