Dakshinamurthy or better known as swamy, is a great music composer.1960-80 is the golden era of Malayalam film music.Swamy,G.Devarajan,Baburaj,M.B.Sreenivasan, they produced plenty of melodious songs.
Swamy is highly knowledgeable in carnatic,he used to give concerts,not only at Vaikom temple(he gives credit to vaikathappan for all achievements he got),but other places also,I have attened his concert at Shastry hall,Chennai.
But surely,he was a better composer than a platform singer
Most of his songs are raga based and he used sankarabharanam,kharaharapriya to lighter ragas like madhuvanthi meticulously.
His songs may be analysed at light classical thread.
