Qasimov began singing professionally while Azerbaijan was still under Soviet rule and the mugham form had not received support from the state.
Performances were restricted and, whilst a few singers aimed to preserve the history of the traditional style, the ruling communist party largely regarded it as a local curiosity.
However, Qasimov's growing popularity was accompanied by declining Soviet influence and in 1983 he won the national Jabbar Garyaghdioghlu Singing Competition.

As his career progressed he was recognised internationally, winning awards at the 1983 and 1987 UNESCO Symposia on Traditional and Modern Art of Central Asian and Asian Countries.
His tours were very well received in his both home country and abroad; as travel outside the Soviet Union was rare for citizens at the time, his tours and concerts garnered much press and many television announcements.
As his career was blossoming, so was his personal life — Qasimov and his wife, Tamilla Aslanova, had their first child in 1980, Ferghana Qasimova, and later had two more children: a son, Gadir, and second daughter, Dilruba.
Despite such changes, Qasimov's background continued to shape his personality and music, dismissing the foreign influences found in cities and television.

Over time, Qasimov's style had developed to include not only traditional Azerbaijani music and mugham, but also ashiq, a rural bardic tradition with roots in Turkey, Azerbaijan and the Azeri region of Iran.
In addition, he was influenced by artists from other disciplines, placing particular importance on Qawwali singer Nusrat Fateh Ali Khan: "When I heard him in concert many doors were opened for me and many questions answered".
His success was all the more impressive for he had broken from the traditional style of mugham and brought his own interpretation to the genre.
He saw this as a way of showing mugham to a wider audience and making it relevant to contemporary society, saying: "The world in which we live changes daily.
Music has to lend emotional expression to this vitality.
I accommodate that by seeking out new paths and interpretations".
Similarly he revolutionised the strict mugham instrumentation, introducing his own improvisation and including new sounds such as the double-reeded balaban (also known as a duduk), the clarinet and the nagara, a metal-bodied drum.
Additionally, he remained conscious of the need to modernise when choosing his ensemble; mixing older, experienced players with younger, more dynamic musicians.

The 1990s saw Qasimov tour widely with concerts in Iran, Brazil, the United States and throughout Europe.
His music gained more exposure in Europe and North America when a chance meeting with American musician Jeff Buckley at a classical music festival in France resulted in a collaboration.
Buckley was a fan of Qasimov's music and they performed a duet of "What Will You Say" which featured on Buckley's Live à l'Olympia release.
Buckley, an avid listener of Qawwali, was highly impressed with Qasimov's performance, noting: "he just came with his drum, and he sang, and it was so pure and effortless... That's what the voice is for".
Qasimov was equally pleased with the collaboration, stating that his American counterpart "was very gifted and had a real feeling for Eastern people."
The performance resulted in the introduction of Qasimov's music to a broader Western audience.

Revitalised by Azerbaijan's declaration of independence from the Soviet Union, the artistic importance of Azeri culture, including both Qasimov and mugham, began to be recognised internationally.
Qasimov was named the "People's Artist of Azerbaijan" in 1993 and earned the highest honour in his field in 1999 when he won the International IMC-UNESCO Music Prize — an award given to high calibre musicians such as Dmitri Shostakovich, Leonard Bernstein, Ravi Shankar and Nusrat Fateh Ali Khan.
Partly helped by Qasimov's extensive touring and promotion of mugham, UNESCO proclaimed the mugham of Azerbaijan a "Masterpiece of the Oral and Intangible Heritage of Humanity" in 2003, reassuring the preservat
