At the Listening Party event, he performed 10 new songs seamlessly, bringing a vibrant atmosphere with the participation of many artists such as Will, Phao, Lyhan, Gi Gi Huong Giang, Emma, Hoang Ton, Do Hoang Duong... Notably, OSAD had a special collaboration with onionn and My My in the song Nguoi Ta Do.
When asked about the pressure of collaborating with producer onionn - who was successful with Son Tung M-TP and MONO, OSAD affirmed that he was "not afraid" but was only a little hesitant at first because he did not fully understand onionn's musical style.
I promote individualism, always believing that each person is a separate individual. When working with someone, I always want to keep my own quality so that the product be strongly OSAD imprint," he shared.



On onionn., he commented that OSAD is an artist who is very hard-working and sincere with music, and hoped that the audience would notice the difference in this project.
The album O_O consists of 15 songs, made by the two artists in more than a year and a half. The unique title is inspired by the familiar emotional symbol of the 9x generation, and is also the two initials in the stage names OSAD and onionn. Each song is a piece in the rapper's journey to maturity, from mischievous, arrogant to profound, contemplative. The music in the album is diverse in genres, mixing House, Hip-hop, EDM, Vinahouse and Vietnamese folk material.
OSAD revealed that he had struggled to make his own music, until he decided to "join onion's hand to find new inspiration and dare to try new things". With their debut album, OSAD wants to prove that "the special thing can be created by ordinary people", sending a message of passion and perseverance.
He admitted that this was a big bet to get out of his comfort zone: After each failure, I want to bet big. I don't know what the result will be, but as long as I do my best, good things will come".
