Madhusudanan Kalaichelvan is so deep in Carnatic Music and he also goes deeper to temple and architecture. He sometimes in chennai does a lecdem with CM vidwans and vidushis. I have not yet witnessed any live programs of his. I have a hunch that he may be writing here too in rasikas.org, but definitely reads. There is a Writeup about him in The Hindu Friday Review, dated Nov 18,2022. Nowadays Friday review is dilution of content only flash announcements .
On. a side note , till say 2017 or so , i did not pay attention to decline of temples , but in the last 4 years i understand slowly how important is for each of us to pool money- atleast do a kovil kumbabishekam and protect temples and with it CM too etc . I and my family did once in Tippirajapuram near kumbakonam (i wrote a review few years back of that when Hyderabad Ramamurthy sang)
