All four brothers were the permanent members of the group and contributed to its success in their own capacity with full dedication. Though the name Sabri Brothers relates to the lead singers Ghulam Farid and Maqbool Ahmed Sabri, the ensemble comprised of two more brothers from the same family, Kamal Sabri and Mehmood Ghaznavi Sabri. This kind of hysteric trance is a side-effect of pure sufi music which they revived and exposed to the modern, urban audience. It was seen many a times that the hypnotized audience went into a frenzy as the brothers continued with their rendition. The intoxicating voices added to their unique style of traditional music made the spiritual experience of the audience wholesome. The champions of this cause were the two brothers Ghulam Farid Sabri and Maqbool Ahmed Shah Sabri who were the lead vocalists in their ensemble and renowned for their original style of rendering in traditional qawwali repertoire. The Sabri Brothers are regarded as the first artists who introduced the art of qawwali to global audience by unshackling it from the limits of local shrines, thereby bringing it global fame with their soulful, transcendental rendition.
