'Indie music' has become quite a fad in India over the past few years. Promoters like Artist Aloud, venues like BlueFrog, channel MTV Indies, the event NH7 Weekender and some radio stations have all done their bit in popularising this trend. And to be fair, a lot of music one hears in this slot is innovative, appealing and very cool.
(Don't be confused between Indipop or Indian pop music)
