Not shocking, but still sad.
STP wasn't quite the soundtrack of my youth, but was the soundtrack of the loss of my youth. "Plush" was on the radio just as I graduated from college and moved to a new city to start life on my own, and about 18 months later I went to an STP concert in Salt Lake City with a few members of a team I was on working in that city. I had a 1993 Ford Probe GT in the early 90s; it was an awesome car and I remember many a very loud STP jam going on in that car.
Thanks for sharing your story, huge bummer today. STP and VR all day!
