Bump, it's been a while but she is working a 3rd album so I've heard. Also, she has a summer tour starting in July 2016. Some shows don't have a personal meet and greet but only sound checks (which is basically a Q&A session along with watching people set up the stage for performance). IMHO, a sound check isn't really worthwhile because one only gets to the venue early, watch people set up the equipment for the performance, and maybe ask a question for Lindsey to answer, just not worth the price.
However, for the shows that have a personal meet and greet (if one can afford it) would be worth it since you would have at least a minute or two of personal time with Lindsey Stirling herself, get a picture with her, etc.
Bump and as her summer tour looms closer, hopefully the ones who are able to go see her, do enjoy the show (and meet and greet if you have a chance to go for that too).
Bump, her new album Brave Enough comes out on August 19th, which exactly 1 week after Comiket 90 (Comic convention in Japan). Btw, if you haven't noticed yet, I'm a Touhou fan.
