Concert Reviews:
​​​​​​​​​​​“The Mridanga accompanist T.R.Sundaresan was very cooperative through out and his performances were excellent. In Reinbeck, Germany. He gave a sampling of Konnakol and morsing, and he was impressive in both. 

“I must particularly commend the Morsing player who uttered the Jathis impeccably and with punch” – Indian Express. 

He demonstrated Konnakol at lec-dem in Berlin and Koln. The audience also thoroughly enjoyed his percussion Tani Avartanam - Sruthi Magazine. 

The Soukhayam and Sunatham in T.R.Sundaresan’s Mridangam is something rare come by. He relished every stroke giving it a melodic lift and rhythmic flourish. His Thani Avartanam in RTP was a refined essay in percussion artistry – Indian Express. 

T.R. Sundaresan’s rhythmic support on the Mridangam with soft and sweet percussion Strokes deserved praise – The Hindu.

“…thereby he, T. R. Sunderesan provided ample rhythmic support to enhance the melodic line …..whether by way of outlining the underlining rhythmic pattern or by inverting it and turning it upside down.” – ‘Eindhoven Dagblad’. 

T. R. Sundaresan amazed the audience eloquently in a gleeful garb just reminiscent of that of the illustrious exponent in ‘Vikatam’, late Thiruvisainallur Ramaswamy – The Hindu.

T. R. Sundaresan extended adequate mridangam support and his Tani Avarthanam was lively, including a few tough passages in Khanda Nadai – The Hindu. 

T. R. Sundaresan’s soft expressions on the mridangam helped the recital move with reassurance on a smooth rhythmic course. – The Hindu. 

T. R. Sundaresan’s soft taps on the mridangam enhanced the aesthetic aspect of the exercise. His tani in Madhyamavathi enlivened the laya patterns – The Hindu.

T. R. Sundaresan gave able mridangam support and played a competent tani avarthanam for pallavi for a difficult eduppu, including many laya patterns. After playing the first and second kalams (three beats and six beats each finger), there were a few passages involving nine beats each finger - can be called tisram in tisra nadai - and the concluding spell was in third kalam involving 12 beats each finger culminating in a beautiful muthaippu. - The Hindu.

T.R. Sundaresan's tani as usual precise as well as pleasant. He matched the Kanta nadai combinations that TNS’s (T.N. Seshagopalan) sang earlier with his own “abiprayams”-

Vocals: Dr M. Balamuralikrishna & Pandit Ajoy Chakrabarty, Violin: Kotandapani Sivaraman, Mridangam: T R Sundaresan, Tabla: Samar Saha, Harmonium: Brajeswar Mukherjee. T R Sundaresan’s tani avartanam was precise and excellent. He played some very complicated patterns in sankeerna, tisra and chatusra nadais with great ease. He is one of those artistes who has the nadam in his hands and fingers.

The Mridangam accompaniment by Mr.T.R.sundaresan was very cooperative through out and his performance was excellent. In Reinbeck he gave a sample of Morsing and Konnakkol, and he was impressive in both.
- Dr.Pia Srinivasan, (Musicologist Germany)

This was moving and spiritual experience that deeply inspired me. The perpose of T.R.Sundaresan's endeavor gradually downed upon me as I sat and watched him play with unwavering freshness and impeccable musicianship, song after song for 42 hours….he made each moment of those 42 hours come alive with vibrant music. This Musical Marathon is a celebration of life it self.
