Mahisasuramardini (Bengali: মহিষাসুরমর্দ্দিনী,The Annihilator of Mahishasur) is a widely popular early radio programme that has been broadcast since 1931 on All India Radio (AIR). It is a one and half-hour audio montage of Chandipath (chanting from Chandi) recitation from the scriptural verses of Sri Sri Chandi or Durga Saptashati, Bengali devotional songs, classical music and a dash of acoustic melodrama. The program has been translated into Hindi set to similar orchestration and is broadcast at the same time for a pan-Indian audience.This programme is aired every year at day-break on Mahalaya. The programme, which started off as a live-performance, has been broadcast in its pre-recorded format since 1958. However, its great popularity remains undiminished even today over 80 years later.
This program has become synonymous with Mahalaya which is celebrated to usher the Debipaksha lunar fortnight and the Durga Puja. To this day, most of Bengal wakes up in the chilly pre dawn hours, 4 am to be precise, on the Mahalaya day to tune into the “Mahisasura Mardini” broadcast. Presently the recordings are available as audio cassettes and Compact Disks from HMV-RPG which has obtained the rights from All India Radio. The CD version (as of 2002) contains 19 tracks
