Raag: Latangi, Composition by Patnam Subramania Iyer (1845-1902)

Aparadhamula,’ was composed in Raag Latangi by Patnam Subramania Iyer (1845-1902). A devotional kriti, this song blends beautifully with the compassionate and courageous emotions of Latangi. Iyer was a prolific and versatile composer who took ahead the musical tradition of Thyagaraja (1767-1847).

Unnikrishnan deftly holds his audience with his soulful and melodious voice, embellishing the kriti with a variety of swarakalpanas .

The raga unfolds with evocative clauses in mellowed nuances, leaving a lingering effect on the mind. Unnikrishnan’s sensitive sequencing of the phrases during the elaboration of Latangi speaks volumes of his refined craftsmanship and ability to portray the raga in its most beautiful light.

Jyotsna Srikanth (violin), Bangalore Praveen (mridangam) and RN Prakash (ghatam) give a refreshing accompaniment adding moments of joy and excitement to this concert.
