The Hyderabad Brothers, D. Raghavachari and D. Seshachari, are the Carnatic music singing duo. Sri Seshachari’s is known for his more robust, deep and resonant singing, and Raghavachary’s rendition is known to be mellow and soft in comparison.Their wonderfully synchronised singing and individual styles complement each other perfectly. Their grip over the Shruti, laya (tempo) and sahitya Bhava is known to be remarkable and their repertoire wide and varied.
Their concerts are often considered imaginative and full of vigor. Their musical skills and style are often compared to that of the legendary Alathur Brothers. Hyderabad Brothers have a distinct style of musical rendition and voice timber which mutually blends well with each other leaving a soothing impact on the listeners.
