To unwind from their academic rigor, generations of IIMCians have evolved an institution within the campus. The name might not be very explanatory but JBS-BaroC is the official band of IIMC. JBS-BaroC nights- with the music, the atmosphere coupled with the "refreshments" - act as escape vents out of the daily chores of IIMC, making them one of the cornerstones of IIMC culture.
JBS stands for "Joka Bus Stand" and BaroC stands for "12 C" which is the number of the bus connecting the campus to the world outside, a metaphor for freedom and fun, much like the band itself. The band does not limit itself to a speicifc genre and plays music ranging from Kishore Kumar's "Humein tumse Pyaar Kitna" to RATM's "Killing in the name of". Their performances are eagerly looked forward to as a time to let your hair down and relax. Their biggest contribution to the institute so far has however been the composition of "Early Days", a song which describes the experience of first two months on campus in poetic detail. No performance of the band is complete without the rendition of this song by the crowd.
