The Ragi Jatha of Bhai Avtar Singh Ji, Bhai Kultar Singh Ji and Bhai Swarn Singh Ji represents an unbroken Gurmat Sangeet tradition that goes all the way back to the times of the Gurus. Bhai Sahib Avtar Singh Ji's father, Bhai Sahib Jwala Singh Ji was an accomplished Ragi, who imparted his knowledge of Gurmat Sangeet to Bhai Sahib Avtar Singh Ji and his older brother Bhai Sahib Gurcharan Singh Ji. Bhai Sahib Avtar Singh Ji and Bhai Sahib Gurcharan Singh Ji have rendered invaluable service to the Sikh Panth by preserving Gurmat Sangeet in its pristine form. They accomplished this by their unwavering commitment to the tradition over the years even as Gurmat Sangeet was being subverted by the pressures of popular culture and film music. The crowning achievement of their career was the publication of 'Gurbani Sangeet Prachin Reet Ratnavali' in which they documented hundreds of traditional Gurmat Sangeet compositions handed down from generation to generation in an unbroken oral tradition.
The Jatha has been renewed upon its being joined by Bhai Kultar Singh, Bhai Avtar Singh Ji's son, who gave up his professional career to return to his roots and propogate the family's tradition as exponents of Gurmat Sangeet.
