I just got an update from Prince Rama Varma's channel (musique4ever) that made my day in the most wonderful way. I am copying the contents and the links here. Raghu mama truly was in a league of his own.
'A mind blowing Thaniavarthanam by Legendary Mridangam Maestro Palghat Raghu and Udipi Sridhar for the Maharaja Swathi Thirunal composition "Raasa Vilasa" which, as far as I know, is one of the few, if not the only composition by any composer which starts at Onnara Edam (Six counts after the first beat) in Randu Kala Chowkam. The challenge posed by this unusual edam inspires the maestros to dizzying heights of brilliance. I offer this video with my prayers as a tribute to Raghu Sir who left us all recently. I wonder whether one would come across a brain like his ever again.'
