My Fav is Bhai Harjinder Singh Ji Sri Nagar Wale.
Sahib Singh may not be knowing it, but yes, he has a vast knowledge of Raags. I have had the honor of doing reyaaz with bhai sahib for sometime. While doing reyaaz, the only style you wil hear from him is classical. He is a real gem. Pakhandi??? he is miles away from pakhand. The man as humble as him and a true gursikh is one of the very few Kirtania who is nitnemi, and does keertan with pyaar.
I remember once in Ludhiana , we invited him to do keertan. That night, he had to rush his mother to the hospital ( she is no more). After admitting her to the hospital he came to do keertan. I think that night, he was so much INTO it that we decided to let him take as much time as he wants. Bhai sahib did keertan for about 90 mins and not a soul moved. He sang a shabad "Dukhia Dardmand, Dar ayea, bahut Pyaas jawab na paya" in such a soulful manner that it moved sangat to tears. He has not recorded that shabad yet.Mind you, he did not come there to collect money. He just wanted us to pray for his mother. He is one of the very few raagis, who still preach and not merely sing.
