The death of Khalid Hossain—a Nazrul Sangeet maestro—will create an immense void in the practice of musical genre. He was not only a musician, but also a researcher and devotee of Nazrul Sangeet.
Khalid believed that the practice of Nazrul songs increased vastly in the last 20 years. He was also one of the torch-bearers to keep the genre alive throughout his long career, spanning over six decades.
The award-winning Nazrul Sangeet singer, teacher, and researcher worked devotedly to preserve the purity of Nazrul songs. Khalid worked on recording the original notations of Kazi Nazrul Islam's songs for five decades.
Six of his albums were on Nazrul Sangeet, one on modern songs, and 12 on Islamic songs. His Islamic Nazrul songs mesmerized listeners for decades.
Some of the best Nazrul Sangeet performed by Khalid Hossain are: “Tobu amare debo na bhulite,” “Amar jabar somoy holo,” “Asile ai bhanga ghore,” “Hat Patese Ay Ghunager,” “Adho Adho Bol,” “Alo ke kabar dhare,” “Chirodin Kaharo Shoman,” “He Modinabashi,” “Kar Monjir Rinijhini Baje,”and “Prosongsha Sobi,” among others.
He was a member of the Nazrul Notation Authentication Board at the Nazrul Institute and president of the Bangladesh Nazrul Sangeet Sangstha.
However, Khalid had great regrets that the Nazrul Institute had done very little to promote Nazrul's songs, due to the institute’s limitations.
Khalid was awarded an Ekushey Padak in 2000 for his immense contribution to music.
