Last night, Widespread Panic kicked off their annual three-night Red Rocks Amphitheatre. While we’ll have a full review of the show coming to you later in the day, in the meantime, we must know: Was Elon Musk at the show last night?!

In the wee hours of the morning, Elon Musk tweeted a picture from the show—specifically, a picture of a Telsa Roadster that was projected during the band’s take on “Space Wrangler” toward the end of the first set. The Tesla Roadster was successfully shot into space back in February with a dummy driver, affectionately named “Starman”; ahead of the vehicle’s launch on the Falcon Heavy, Telsa released a now-famed animated simulation that featured David Bowie’s “Space Oddity”. The recently posted image of the Tesla car projected behind the Athens, Georgia-born jam giant also featured a “Don’t Panic” bumper sticker, which Tesla added as a reference to Douglas Adams’ famed science fiction series, The Hitchhiker’s Guide to the Galaxy, but obviously, took on even more meaning during the Red Rocks show.

While it’s likely that Elon Musk was simply sharing a picture of the Tesla being projected during Widespread Panic’s show, it’s not necessarily totally impossible that Musk himself was at the show. Elon’s brother, Kimbal Musk, lives in Boulder and owns The Kitchen Cafe, which has a number of community restaurants in Colorado, plus other areas in the midwest. Plus, we all know that Elon cares about music, given that he’s reportedly dating the Candian musician and artist Grimes.
