After learning to play piano, she studied traditional Persian singing under Pari Meleki and Mehdi Fallah. She also studied setar with Ramin Kakavand and Masoud Shoari. In 1993, she entered Tehran University obtaining a BA in Music from the university's music faculty, working alongside Sharif lotfi, Ahmad Pejman, Hooshang Zarif, Behnam Vohdani, Abdorreza Sajadi, Houshang Kamkar, and Mohammad Reza Darvishi.

As women are not allowed to sing in public as a solo singer after 1979 Islamic Revolution, most of Mahsa Vahdat's albums were recorded outside Iran where she enjoys great fame with the Iranian diaspora and in world music circles.^[1] In Tehran she teaches Persian vocal music in her home.

Following her participation in Lullabies from the Axis of Evil (2004), Mahsa started a long lasting collaboration with the Norwegian record label Kirkelig Kulturverksted (KKV) and producer Erik Hillestad, which led to a world wide release of a series of records. The album was conceived as a humanistic counter to former US President George Bush’s assertion that Iran, North Korea, and Iraq constituted an axis of evil by showcasing music from these nations. It also included musicians from the Palestinian territories, Afghanistan, Syria, Cuba, and Libya – the latter three of which were identified by Bush's Undersecretary of State and later National Security Advisor to the Trump White House John Bolton as ‘beyond the axis of evil’.^[2]

Since 2007 Mahsa has been one of the ambassadors of Freemuse [de], an independent international organization that advocates freedom of expression for musicians and composers worldwide. In 2010, she was granted the Freemuse Award.

Since 1995 Mahsa has performed as an independent artist in concerts and festivals in Asia, Europe, the US, and Africa together with musicians from Iran, Europe and America. Mahsa Vahdat has worked with many acclaimed musicians in the world such as Tord Gustavsen, Knut Reiersrud, Pasha Hanjani, Atabak elyasi, Shervin Mohajer, Mathias Eick, SKRUK Choir, and Mighty Sam McClain.

In 2007 she recorded "Songs from a Persian Garden" in a charity concert in Tehran in the residence of Italian embassy in cooperation with UN for disabled children in Zahedan and it was released in 2007 in Norway and Europe and America. It was a mix ensemble of Norwegian and Iranian musicians together with her sister Marjan Vahdat as another lead singer. It has been arranged by Knut Reiersrud (Norwegian guitarist and musician). In 2008 she released the I am Eve album with her sister Marjan Vahdat that has a strong message for women in Iran; eg the lyrics of the first track "I am Eve" strongly expresses the power of women who have many restrictions under the Iranian government.

The album received many attention in world music societies and people in Iran and excellent reviews in world music magazines such as fRoots, Songlines and many other reviews.
