Soni Chaurasia, a Kathak artist, has set the world record for the longest dance by performing Kathak continuously for more than 124 hours in Varanasi on Saturday. Her name will now be registered in the Guinness Book of Records. Chaurasia broke the record of Hemlata Kundalu of Trichur, Kerala, who performed Mohiniattam (a classical dance) continuously for 123.20 hours. She started her effort on April 4 at 6pm under the guidance of her teacher Rajesh Dogra and reached the milestone on Saturday late evening.
