I liked the story, the investigation of the corrupt music executives, and the custom group of roadies and such. The lighting techs were obnoxious but just enough to make me think about taking them out first.

I did think the Enraged Supa Trolls and the ambushes of katana wielding Bodyguards made the story arc too hard for a lowbie. I played a level 9 scrapper and routinely got clobbered by those, I had to hospital 4 times and after running back a few times I made sure to eat 2 lucks any time I fought 2 or more Supa Trolls or Bodyguards.

The Supa Trolls were tough because they would all Knockout Blow my character (as seen above); getting KO Blow'd once isn't too bad, but if two trolls are doing them one after another, I'm pretty much toast. The Bodyguards just did a lot of DPS against me, and floored my defense with their attacks.
I probably would've been OK if I were higher level, had more attacks and mez protection maybe (the holds from KO Blow really got me). With the level range of the arc being 1-25 I think this would've been even worse for a level 1. You might consider either raising the min level to be around 15, or else making these mobs easier (maybe mixing the Supa Trolls with more normal Trolls?).
Anyway it was fun, and I did level to 10 and get some badges. Thanks for the arc!
