Every year, more than 6 million people attend live music events in the UK. Festivals are no longer about peace, love and LSD – they're commercial success stories. But have they kept any of their rebellious spirit, or are they just Instagram islands where anything goes?

Not all festivals are about rocking up wearing your least-loved shoes in preparation for the mud. And increasingly, organisers are pushing harder to turn festivals into lifestyle events. This couldn’t be truer for California-based Coachella, and a collaboration with H&M is emphasising this shift.

Discovering new music was once a preserve of A&R scouts at major labels. But with unsigned acts now playing to anyone with an internet connection, how can music fans be sure of who was there first? A new Spotify feature is quantifying ‘cool’, giving music geeks the bragging rights they deserve.

Music fans may not buy as many albums as they used to, but they’re still supporting their favourite artists and discovering new ones via festivals and services like Shazam. In the second of our two-part series we explore how live music and data mining are shaping the future of the industry.
