TK Rangachari is an extraordinary vidwan, not an ounce of intense classicism is ever lost. His grandson DB Ashvin has written a nice pdf about the doyen

Also few great disciples of TKR which is a relevant snippet
"He trained many musicians including the late Vairamangalam Lakshminarayanan who accompanied him in several concerts spanning three decades. His other disciples included Neela Ramgopal, Neyyatinkara Mohana Chandran, Malini Kasturirangan, Jaya Krishnan, Palghat Ambi Iyer, and Sadagopan. Heis survived by five daughters and three sons "
Finally one grand son DB Ashvin is taking up pristine carnatic after his grandfather, after possibly no takers with 7 kids of TKR and may be all other grandchildren. I see one of TKR daughter Mallika Jayanth Kumar did take up some thing in cm ,not sure what that is.
On a sidenote Trichur Brothers paramaguru is TKR as their guru is Neyyatinkara Mohana Chandran
