The evenings are notable for the "Pro-Nights", more commonly known as Star-Nites — the biggest events in Spring Fest which usually involve live concerts by some of the most famous musicians and bands of national and international acclaim. All the Star Nites are free to attend for any student of the institute and all registered participants. The genres of music are wide and varied and involve pop, rock and fusion bands. The venue for these events is the Tagore Open Air Theater (TOAT) and Jnan Ghosh Stadium which usually get packed to their full capacity during the Star-Nites, with crowds of up to 23,000 people. Famous Indian artists like Armaan Malik, Sachin-Jigar, Shalmali Kholgade, Farhan Akhtar, Amit Trivedi, Salim-Sulaiman, Pritam, Kailash Kher, KK, Papon, S. P. Balasubramaniam, Shaan, Sunidhi Chauhan, Vishal-Shekhar, Shweta Pandit, Shankar Mahadevan, Shivamani, Sukhwinder Singh and classical performers such as Pandit Debashish Bhattacharya, Pandit Hariprasad Chaurasia, L. Sriram, Pandit Vishwa Mohan Bhatt, and Pandit Divyang Vakil have performed here. Bands like The Local Train, Coshish, Order of Chaos, Pentagram, Swarathma, Underground Authority, Kryptos, Parikrama, Euphoria, Indian Ocean, Strings, and Spunk have also performed.
