In addition to her intense rehearsal and study schedule at the college, Nune performed regularly at Grigorian's Yerevan jazz club, "Azad Jamantz".

Under the direction of famed composer and conductor Constantine Orbelian, Nune performed with the Orchestra in Armenia and throughout the former Soviet Union, singing Armenian folk songs and jazz standards.

Nune won the highest possible scores from a panel of judges, retained the title of "top female vocalist" for the entire length of the television season and quickly became a household name in Armenia.

After the fall of the Soviet Union, harsh economic conditions in Armenia forced Nune to seek employment opportunities abroad.

During her concerts and small-venue shows, Nune sang contemporary hits, pop and jazz standards and songs in English, Arabic, French and Armenian.

Because of her hit music videos and popular CDs, Nune sold out her first concert in the US and enjoyed unexpected and unprecedented attention during her appearances at Armenian schools and record stores.

In 2001, her concert in honor of those who lost their lives during the September 11 attacks, was attended by nearly eight thousand people and mentioned on the CNN "World Report" and the Mir and Associated Press television news services.

Nune's most notable concert venues have included the Hamaleer Sport Complex in Armenia, the Universal Amphitheatre in Los Angeles, the Kodak Theatre in Hollywood and the Lincoln Center in New York City.
