Thotakura Somaraju and Saluri Koteswara Rao, popularly known as Raj–Koti, were a duo of Indian film music composers, singer-songwriters, record producers, musicians and multi-instrumentalists in Telugu cinema. In a notable career spanning a decade, the duo garnered particular acclaim for redefining contemporary Telugu film music. They composed music for about 180 films. Out of their 3,000 songs, about 2,500 were sung by the singers S. P. Balasubrahmanyam, P. Susheela and K. S. Chithra. The Raj–Koti duo was among the many prominent South Indian composers for whom A. R. Rahman has worked as a keyboard programmer for 8 years. In a television interview aired on ABN Andhrajyothy, the duo announced that they were teaming up again in 2012 and reinstating the Raj–Koti brand.
