Sunil Sufi, a renowned singer and music professor from Himachal Pradesh, passed away yesterday at Tanda Medical College after a prolonged illness. Loved for his heartfelt renditions of Himachali folk and Sufi music, he gifted timeless melodies like "Mata Kangra Waliye" and "Sone Mukhde Da Lein De Najara" that continue to echo across the hills.
