In a world where most people spend their lives in some sort of AR, many bands wouldn’t even have instruments. They would use AR versions of them. They may never leave their couches/garages, just “telecommute” to their gigs. Heck, many may find actual live bands off-putting. Too loud (you can adjust the volume in AR), too personal (“They were sweaty and smelly, and jumping up and down aggressively-Should I run?”)
Through AR, the concept of bands may disappear. Imagine a world where Guitar Hero meets League of Legends. Thousands of people “competing” in battles of the bands, all while sitting on their couch. And the top competitions watched by millions of fans/enthusiasts. With millions of nuyen in prize money and endorsement deals, are your players ready to “swat” a contestant for a big payday? That contestant could be anywhere in the world, so just finding them will be a big job. Then you may have to fly halfway across the world to find them. Whether you kick down his door, or just jam his signal is up to them and their Mr. Johnson.
Instead of live gigs, the bigger bands may do special “holo drop performances”. They send a truck to some cool or meaningful location (a beach in Ibiza, a spot in the desert, a corner in a distressed neighborhood in Manhattan), the truck sets up a holo projector, and the band does a one-off performance. Perhaps some shadowrunners are needed for security, or are hired to disrupt the gig...
Bands would also rise and fall in popularity much quicker. In a 24-hour news/entertainment cycle world, a song may hit the heights during the morning work commute, only to be replaced by dinner time (or even lunch!) Longer term fame may only exist through the “balkanization” of music. With music available electronically, any genre is available to the entire planet with the touch of an AR button. Into elf poser grunge neo-metal? You and the other couple thousand fans can listen/download to your hearts content, instantly and exclusively. This could help runners. Is your extraction target into Dutch glam dragonic chants? Check out who is streaming that live in the facility you just infiltrated and follow the music to its source, and your payday...
