Dr Ganesh, is the disciple of maharAjapuram santhanam. His concerts remind you of shri santhanam. Of late he is also performing as a nAmasankeerthanam artist apart from him being a carnatic vocalist.
Below link is SVK review of his concert in The Hindu.

I cannot get it when SVK says "From here started the hurried presentation of “Amba Vaani” (Keravani) and “Sakala Graha Bala Neene” (Atana) in compelling and combative flashes".
Few krithis like amba vAni in keeravAni have a bit of hurried tempo and sakala graha in atAnA also have a bit of fast flashes .
