I read something a while back about a nightly music and light show on the fountain, but I can't find info on the website. Is it a thing of the past?
It's not a show per se., they just have fountain lighting synced to music for a while in the evening. I think if is still working, although the fountain was under repair for a while, so not sure.
If your visit is today, you will get a much better show tonight. Pride fest is this weekend and the fireworks display tonight, is probably the best one of the year.
