Sithara's journey into the world of music began at the tender age of four. Little Sithara used to imitate and hum along songs with her father with immense interest, and her enthusiastic parents decided on developing her vocal skills. Her early gurus Sri Ramanattukara Sathish and Pala CK Ramachandran nurtured her talent and helped mould her into a fine Carnatic music artiste.
Music has been a companion for Sithara, in both good and bad times. She always found inspiration in music, be it Indian Classical, Sufi, Jazz or Blues. Hailing from a family deeply involved with Carnatic music, she was the first one who set out to pursue singing as a career and thus widen her knowledge horizon. Later on, Sithara started her formal training in Hindustani music under Sri Vijayasenan and Ustad Fiyaz Khan, which she is still pursuing.
As an artiste, she has performed at numerous stage shows: Hindustani, Carnatic and Ghazal concerts in and outside India. For her, the sense of excitement borne out of the emotional connect with the audience is priceless. She loves experimenting with genres like Pop, Folk and Fusion, which has made her well-liked among traditional and new generation listeners alike. Sithara's desire is to learn and explore the cultural aspects of different schools of music. A Post graduate in English Literature, she also holds masters' degrees in Hindustani Khyal music and Vocal music from Rabindra Bharati University, Kolkata.
She launched her musical band Eastraga which focuses on a mix of female oriented songs backed by a team of renowned musicians like Rison, Sushanth, Abhijith Sreenivasan, Paulson, Thanuj, Jitu Oommen Thomas and Sarfaraz Khan. The band made their first performances at JTPac, Thripunithura followed by a gig at Pariyaram Medical College along with Sachin Warrier, Job Kurian and Roopa. In 2017, she recorded a single titled Ente Akasham, dedicated to femininity. The work is her two-month-long effort to picturize the life of night-time female workers. The single written and composed by herself maps the common thought process every woman passes through than straightaway speaking about the atrocities against them or an awareness creation in that sense. The official video was released at a programme held by Kerala State Women’s Development Corporation to commemorate International Women's Day in Thiruvananthapuram.
