Here's a crowd-shot video of Styx performing in Phoenix, Arizona in 1997. This show was apparently filmed with a 9 camera setup but likely got permanently shelved when Dennis departed the group. It was the first tour that Styx used lasers!
The crowd is absolutely ecstatic the entire time, singing along to almost every song... the crowd cheering "Tommy! Tommy! Tommy!" half the time... I'd love to see the video or hear the recording they made of it come to light but it's likely to stay in the archives forever.
Anyways, happy Sunday!
