Beginning in 1993, Choudhury started recording harmonica albums featuring Salil Chowdhury's songs. Choudhury's final tribute to Salilda was recorded just after his death in 1995. Afterwards, Choudhury began researching his unreleased work from the '40s and '50s. In 2010, he released Songs of Consciousness, an album featuring many of Salilda's rare songs. A second album of unreleased songs, featuring compositions written just before Bangladesh became independent was produced and released by Choudhury in 2011.
