O-Zone is a Moldovan Eurodance and pop music group that first gained international fame in the early 2000s.
Originally formed in 1999 as a duo, the band quickly became a trio with members Dan Bălan, Radu Sîrbu, and Arsenie Todiraș. They skyrocketed to global popularity with their 2003 hit single "Dragostea din tei," known worldwide as the "Numa Numa Song." The catchy tune and their album DiscO-Zone sold millions of copies across Europe and Japan, making O-Zone the first Moldovan act with such wide-reaching success.
Despite disbanding in 2005, the group reunited briefly for concerts in 2017 and 2019. In 2024, O-Zone returned as a tribute band featuring Arsenie Todiraș with two dancers, continuing to celebrate their iconic music legacy. Their unique blend of upbeat eurodance and pop secured a permanent place in early 2000s European pop culture.
